I understand that. And part of my error was waiting until it was a big thing for me to bring it up, like it had been bothering me for a year and a half. If I'd brought it up much earlier, likely wouldn't have been a big thing either way. It's just interesting now that he stands up when I leave pretty much no matter what--even if I forget to pay at the beginning, or if he forgets I paid at the beginning then sits at his computer expecting me to pay. If the latter happens, now he just stands back up, opens the door, and holds out his hand to me. It's like he realized it was important to me and does it anyway, despite any potential inconvenience. And he tends to mention paying at beginning if I forget so that we can do that (as then he'd just get up from his chair, open door, then shake my hand, vs. sitting first). Like he seems to make an effort to do it now, even though I haven't mentioned it at all since that conflict months ago (I really haven't, even one time when he sat and stayed sitting). So I feel OK about it. And at the time, I was making a request, which can be hard for me to do--I didn't intend to be controlling. So that's part of what was so difficult about it.
