Do You Have To Be Friends With Your Co-Workers ?

I think that you don't necessarily have to be friends with your co-workers. You just have to be able to get along with them for whenever you need help with something at work. You can't really be friends with a person you know at work, but not off work. What if their not what you expect them to be out of work ?Sometimes becoming good friends can lead to a bad thing. People can sometimes change eventually.
