Describe a disagreement you had with someone

I'll describe a disagreement I had with a close friend of mine, someone I've known since school, over how we were planning a trip the two of us were taking together last year. It was about budget, essentially — she wanted to book a fairly expensive hotel in a good location, and I wanted something cheaper further out, partly because I was trying to save money at the time for something else. It started small, just a slightly tense conversation over messages about which place to book, but it escalated a bit because neither of us said clearly what was actually bothering us — I didn't say I was tight on money, and she didn't say she just wanted the trip to feel special after a rough year at work, so we ended up arguing about the wrong thing entirely, hotels, instead of what we each actually needed from it. It got resolved, in the end, only once we sat down and had an actual conversation instead of texting back and forth, and once she explained her reasons and I explained mine, the disagreement basically dissolved because it had never really been about the hotel at all. We ended up compromising, a mid-range place that worked for both budgets, and honestly the whole thing taught me that most of the arguments I have with people close to me are really about something underneath the surface issue, not the surface issue itself.
