I guess i am just repeating a lot of the other posts, but you definatly need to learn where to draw the line. I recently worked a summer SM for a small melodrama with a small cast. All the cast lived together in 2 apartments as well as had to work together, so you can imagine there we times they wouldn't be getting along. Some of the cast decided that they should tell me everything about why a certain person was pissing them off, or what they did on stage that bugged them. I just had to keep my mouth shut and let them vent it. Not once did i offer my opinion, and when they would ask me, i would just say "sorry, but i don't want to get involved". They were all very nice people and we would hang out, but you should never accept or add to gossip, or talk about work when you are out.
