"Friend" has multiple definitions, including:

> someone who is not an enemy and who you can trust

Here's another:

> a person who you know well and who you like a lot

Don't you think it's beneficial to trust and like your colleagues? I personally find it helpful. Few of us do jobs of our dreams, so having friends at work is nice. You don't have to invite them to your birthday and family events to call them friends.
