I'm not really the sort of person who gets overly exuberant at concerts either. I might sing along a bit, but I mostly just sit or stand there and take it in. I love the music and I wouldn't go if I didn't love the artist, but I don't feel the need to bounce around like a drunk coed! I've started to try and take a pause before I reply to emails. That's probably my biggest issue. I come off as crass otherwise, which isn't the way I want my coworkers to see me.
