Yup, I get far more value out of things where I can see a few people I really like than a whole group that I'm less close with. And structured fun really helps there too.

Took me quite a while to switch from "I have no friends! Find more and attach to them all!" to "I have waaaay too many friends to see regularly, stop going to everything!"
And now I barely go out at all, and mostly spend time with Jane and Sophia. Although I expect to occasionally make it out again at some point.
