LOL, keeping yourself busy with unavailable men drama is a good one
I'm not single, but I'm not married and have no kids. I never really wanted that anyway, but it is weird to see your friends do these things-- it seems like everyone around me is having babies or celebrating milestones with their kid.
I think Facebook is very bad for making people feel insecure about their life choices and circumstances. Most of the friends I see on a regular basis are also childless. If I didn't have Facebook, I am not sure I would notice as much.
