The trigger yesterday (a new guy being loud) happened again today. Yesterday, he was relating an anecdote, and the end of it was basically yelling STOP IT. The leader could tell pretty quickly we had been triggered badly. She asked "are you ok?" and all I could muster was "that was loud", barely above a whisper. Today, there wasn't any real one thing, he is just a loud, somewhat powerful personality. He did, at one point, laugh, but it was one of those short kind of laughs (like what I would type as "heh") and it was too loud for me. I'm supposed to be done with the group next week but I don't know if I can handle this guy that long.
