That was a little off topic, but back to the topic on had. Sometimes people aren't having a great day and they take it out on someone else, possibly someone in the team. That has happened to me once, and I didn't feel so great. Anyways, communication is a great way to work out problems (as someone mentioned, I think). And just being friendly overall will improve the overall atmosphere. Personally I try to be friendly to everyone and just have a smile on my face. It's really had to pick a fight with someone who refuses to fight. And always be there if a fellow team member just needs to talk about anything.
