Caring is a big one. And for that I may just tell them Im socially handicapped jokingly and then immediately I stop caring and become more social. Sure, there are some limits, I still have a hard time being at large parties where the noise is disorienting and find myself stepping out for some fresh air more frequently. These interactions drain my batteries but are sometimes necessary.

I can’t really recommend it because of how likely you are to do something stupid but lots and lots of alcohol fueled socializing is how I leveled up my social skills over the course of one summer. It also caused an audible change in the prosody of my speech, going from unusually monotone to more expressive.
