I've had a pretty good working relationship with my boss for the past 1 1/2 years. He trusts me to deal with the problems he gives me, I give him the best quality work that I can, occasionally there are some hangups but in general I do good work for him, he appreciates me, and we get along well in the office.
A short time ago, while I was at home, I noticed my boss's name on Facebook, as an invitation to become a Facebook Friend with him.
Now, I don't normally post racy or inappropriate things on my Facebook (I have my family to discourage me from doing that), and I don't usually post inflammatory work-related things on it either (because I know better than to do that), but I am a bit of a nerd and I don't know if my boss's political leaning is in-line with mine (I think it is, but it hasn't really come up).
Do I have anything to worry about? Is it appropriate to accept this invitation?
Note that I don't ever go on Facebook during work, even during hours when nothing is really going on, because I know sometimes my Facebook Friends might post something that is not work-appropriate (again, nothing really racy or inappropriate, just inappropriate for a work environment).
