Me: no thanks, I'm going there later to do some shopping myself
Aunt: But we could combine trips! It's wasteful to both drive there on the same day! The responsible thing to do---
Me: ok, I give up. Please get me cat litter and cat snacks.
Aunt: Ok!!!! :)) Which ones? And what isle? What color is the package---
Me: exasperated Are you serious? I caved and gave you what you wanted. Now you're asking for more information? I told you I wanted to do my own shopping, and you fought me on it. I'm making a peace offering by giving you two items to buy for me, and you're saying I need to go find the names and package colors and isle numbers? Please just be satisfied with what I gave you.
The thing that she wants is to feel good about buying me something. But I don't want that. That's the disagreement.
I imagine most people would see me as the asshole here: she can't buy the right item if I don't tell her what it is. But I clearly don't care about those details; if I wanted something specific I would have told her that. The only reason I mentioned them was to appease her. I'm giving her something she wanted, something I wanted for myself, and she's demanding more.
Are you the same person as Crackhappy? I was asking them for details about their answer. I'm not sure if your instance allows multiboxing but if not you might consider logging in with the correct account before posting.
