I've been using FaceBook for a few months and I recently got into situations where I don't know what to do.
The first one: I got a friend request from someone I don't know. We have 1 friend in common but I'm not very close to that friend and I can't ask him why one of his contacts wants to be a friend of mine. I sent her a message asking what's the deal but she didn't answer me. What do people usually do in these situations? Just add friends to collect as many as possible?
The second: I found people who used to be friends of mine a few years ago (or many years ago) but we're no longer in touch. The relationships didn't end in a bad way, we just drifted apart after we stopped working in the same place. Are people usually happy to get contacted in such situations, or will they think that since we're no longer friends in real life there's no reason for us to be friends of FaceBook?
