absolutely. i get drained so easily. there's this one NT at my work (and when i say NT i mean quintessential NT, big, loud, mean, alpha, extroverted, bully) who, for some reason, keeps bugging me to go to chicago for the day with her (that's where i'm from) and i just can't get myself to do it and don't know how to tell her no. i can't even imagine the absolutely draining HELL of having to "act" for that long. she's ok in small doses when you want to make silly pop culture referential humor but apart from that one cool point, she's a bigoted, ignorant, loud, middle-aged stoner. with a mustache. this is one of those people who let me know on my first day of work "you're too quiet". uh, no kidding sister, i close down around people like you.
