I’ve met nice people in meetup group, group fell apart but 4 of us remained friends, we see each other at least monthly (going to a movie and lunch this Sunday) sometimes more often and we also do annual vacation/trip together. I have other people I hang out with but they are more of acquaintances.

I am not introvert really, I am a social person and am always doing something with others but I don’t easily make close friends. I don’t easily let people in.
