Are you friends with your boss?

It’s good to get along well with your boss, manager, supervisor, whatever.  Do you ever chat with them about non-work related things?  Probably pretty common and it’s fairly safe.  Do you interact with your boss outside the office?  Less common I’d guess.  Are you friends with your boss on Facebook?  Apparently up to 20% of people are.  Are they crazy?  Isn’t that what LinkedIn is for?

I’m pretty circumspect with what I post on Facebook, but I believe in the separation of work and home.  Boundaries can be a good, healthy thing.  Where do you set your boundaries?  Have they changed over time?
