Socializing wears me out more than anything, even if I'm careful not to stand around. I don't know how much of my fatigue/partial paralysis afterwards is due to the emotional strain, and how much can be accounted for by just the physical strain itself. I'm rather shy, so talking to people makes me tense. Physically tensing your muscles, even just a bit, for a long time causes muscle-fatigue/partial paralysis. Similarly, my biggest trigger is going to church. I really haven't figured out why, exactly, but I suspect it has to do with sitting "at attention" for an hour.
