I agree with so many people here that I want my friendships to be marked by general consideration rather than tit-for-tat reciprocity. I brought enough executive function for the whole class. I am super-organized, and my house is always basically clean enough for company. I am comfortable with cooking for a variety of dietary needs and keep separate food prep items to make sure that can be accommodated. Does that mean that I don't value the friendship of anybody who isn't in the same boat? IT SURE DOES NOT. And I would hate to just stop inviting people over because their apartment is only big enough to seat them and their kid, not me--or because they're not comfortable cooking and can't afford takeout--or because they're ashamed of the mess--or a million other reasons.

I'm allergic to cats, and most of my friends have cats. So other people come here WAY more often than I go there. Because in an actual friendship you can open your mouth and talk about what works to make everybody feel comfortable and cared about.
