Suppose your boss has sent you a friend request on Facebook. Instead of immediately rejecting the request, it is better to learn how to create friends lists on Facebook, because that way you can control who sees what on Facebook. Then at least you know for sure that your boss doesn't see what you were up to in the pub last night.
Steps
