The Grocery Store Lesson
I remember the lesson; In fact, it would be impossible for me not to.
I felt embarrassed, guilty, defensive, frustrated and in some ways scared.
Part of me couldn’t fathom that this is what my life looked like now; the other part desperately wanted to make sure it continued to. It was a new level of cognitive dissonance—I was truly having an internal battle trying to reconcile these opposing feelings.
I was a new wife, 22 or 23 years old, either it was our first or second year of marriage. We were still trying to figure out what that meant. What that looked like. Who we were and how could two people become one? Especially when we both looked at the world from such different perspectives, backgrounds, and to some degree values, was it even possible?
I had gone to the grocery store on my day off from the dealership—Aldi because it was the only store that came close to letting me follow our household budget for groceries.
Our weekly grocery budget back in 2012? $40. (It continued to be for almost a decade)
That was it. $40.00
We were pretty staunchly Ramsey plan back then and we used the envelope method on and off over the first few years of marriage to train ourselves (mostly me) how a budget worked. I guess this was one of the times where we were following the budget but using debit cards…
So I filled up the cart with the items I needed for the week and plugged the costs into my phone calculator as I went. Well as I was getting ready to pay the cashier said $43.11 was my total. That meant I had either forgotten to add something to my running list, I had put in the wrong price or something had been mispriced. I had a decision to make and I didn’t even consider at the time what the consequences of each outcome might be. I had a surge of guilt, I didn’t want to over spend on the budget, but at the same time the thought, but 3 dollars isn’t really a big deal (see how the 11 cents gets dropped off to make it that much more innocent?) so I put aside the feeling of guilt and put into place the justification. I swiped my card.
It was just $3.11.
$3.11.
Not the end of the world.
I was very close to the budget.
I paid and left.
When $3.11 Became More Than $3.11
I don’t remember exactly when the conversation occurred after that. But it did. We had a joint bank account, and I wasn’t trying to hide anything, at that point, I felt justified.
Just $3.11…
I imagine it went something like, “By the way, the groceries were $43.11.” Or more likely, I said nothing and handed him the receipt. I would have known (we’d been together since 2009) that there was a serious chance that my just $3.11 wouldn’t be a “just” to him.
And that’s when it felt like the world was ending.
My husband didn’t yell, but he also didn’t make room for my justification. There is either you stayed on budget, or you didn’t.
That’s it.
Because that is the reality of money. Of a budget. Of doing anything really. Either you did it, or you didn’t do it.
I didn’t do it.
That surge of guilt I had had, that had tried to warn me, tried to spare me this conversation… It reemerged.
It felt like the end of the world. I was still so young and insecure about myself, about our relationship, so overwhelmed with fear that he would leave, or that I would do something to damage our budding marriage. Things 15+ years of marriage now have dulled, but back then? It was a sharp and painful fear.
He wasn’t always as understanding as he is now; he didn’t know me as well, and all he saw was this young wife who had a history of overdrawing her banking account, going over the set budget. (I intentionally am not going to say “agreed upon” because that would be misleading. What was agreed upon was that we were married. And the budget was a reflection of the funds that we had. I was made aware of it at the time. And I was happy to agree with a healthy vacation budget and a large “out to eat” budget but I was still too inexperienced and prideful to acknowledge that meant there was less money for other parts of the budget, including the weekly grocery budget.)
What happened was a lesson from a man who had a much more solid grasp of personal finances, a man who had long before determined never to be “broke” again, and a man who was working to become wealthy. What he needed his wife to understand was the reality of the systems that were in place.
The budget wasn’t a suggestion. It was a reality. A fact. Solid. Something we had discussed, something I was aware of, and something I had ignored.
It was that action, ignoring it and going over, that pointed out to him I was not taking it seriously. I had given my word when I became his wife that I wouldn’t defy what was put into place. And so maybe I didn’t agree with the budget, maybe my justification when I made the decision was also rebellion. It was definitely flippant and disrespectful. I showed with my actions—and without much thought—that I was willing to break the system.
At the time, all I felt was hurt, confused, and to some degree rejected.
Couldn’t I, in the moment, make decisions about our money?
Wasn’t I worthy of trust?
Why was $3.11 such a big deal?
Why couldn’t he just get over it?
What Was Really Being Built
I understand now—although it did take me a long time—that it wasn’t about the $3.11. It was about the system. It was about me as a partner in building that system.
We were newly married, and we were building our lives together from the ground up. There were some leftover flawed systems and processes that I was used to working from and was trying to fix… and replacing old habits was difficult.
I chose to see it as not a big deal, but in reality, I had opened a door that made my husband question if I was reliable.
In Proverbs 14:1 we read: “Every wise woman builds her house, but a foolish one tears it down with her own hands.”
I had been given an opportunity to build up my “house”, to stick to the systems we were creating, and in that moment when I decided, my judgment, my pride mattered more, I failed. It was selfish and a reflection of old broken systems trying to embed themselves in our new life.
This decision could have created many problems because in that moment, by stepping outside the agreed budget, I was undermining that structure.
This created more problems than the $3.11 itself.
You can’t manage chaos. You can’t measure what isn’t consistent. And you can’t build trust with someone who repeatedly doesn’t do what they say they will do.
Fortunately, my husband has always been very good at systems and structure. He had a solution. He made it very clear that what had happened was a disruption to what we were building, and it wasn’t acceptable and must be corrected.
At the time, we didn’t communicate as well as we do now. He would have wanted to make sure that I understood that there isn’t ever a justification for spending money that didn’t exist. I am certain that I got overly emotional (because I still do, although not like I used to.) I am also certain that I attempted to dig in my heels, because I still do that too when I don’t fully grasp the importance of something, or don’t agree. Back then, that would have created an argument; now he understands me and is willing to live with me in an understanding way. So while the outcome is the same, we skip the argument portion, generally.
Back to the $3.11… I felt defensive. Like what I had done wasn’t a big deal. Again, it wasn’t about $3.11, but I had myself convinced that it was.
Eventually, it was “decided” (read, I was told) that I would have to return an item or items equal to or greater than $3.11 back to the store. This was my opportunity to make it right. It was my way to prove that I was willing to do what I said, and was willing to stick to the system.
I felt embarrassed, guilty, defensive, frustrated.
But I did it.
Learning to Live Inside the System
I was mad for a long time. And I was mad because I was blind to what the extra money represented.
I had been taught that you could say one thing and do another as long as it wasn’t “harmful,” or as long as it was “close enough.”
But that system is flawed. It’s unstable. It breaks over time.
If you don’t put workable systems in place, you cannot be successful. You can’t measure progress. You can’t build trust. And you can’t consistently move toward anything meaningful.
That was the lesson I began learning that day.
And I didn’t learn it all at once.
Even after that moment, I struggled with it but I began to understand and agree that staying within the budget mattered more than my pride. So if I went over while I was checking out, I would ask the cashier to remove an item. I hated it. It was uncomfortable and embarrassing in the moment, but it was part of honoring what I had agreed to do, who my husband was asking me to be within this system we were building together.
Over time, I learned how to consistently come in under budget. I learned what to buy, when to buy it, what to skip and how to cook with a few ingredients. (More on that in a coming article)
What started as a $40 weekly grocery “constraint” became a long-term skill—one I worked with for nearly a decade. In recent years that budget has doubled due to rising food costs, but the underlying skill has remained the same. Even after having two children, we still maintain a relatively low grocery budget, because it’s a habit, a skill, a system we have tested and know works.
Testing Systems in Real Life
Yet even now, we don’t always get it right.
I still have the same instincts I had at twenty-two—the belief that “close enough” should be enough. I still push against the budget, question the decisions, complain the grocery budget isn’t enough but it’s more of a running joke now more than anything. And my husband is still often the one keeping the budget aligned with our goals by keeping the end in mind and building systems around it.
But it’s important to note that it goes both ways. There are moments when he wants to take on a car loan for a CTS-V, and I say no. Not because I don’t want one as well but because when I push back it tests our resolve to upset our whole system to include a car loan. (click here to see how much yours is actually costing you)
It is not about perfection.
It is about awareness.
About two people learning each other well enough to know where the system holds, where it bends, and where it needs to be rebuilt.
We are not living inside perfect discipline. We are living inside a relationship where systems are shared, argued over, refined, and sometimes resisted—but always returned to.
And that is what changed everything.
That is what led to Sailing Terra Firma.
Not as a finished answer—but as an ongoing record of how two people build, test, break, and rebuild the systems that shape a life.
Starting with $3.11.
