So tonight I'm gonna stay in on my own and watch TV. This is entirely my decision (there were 2 places I was invited out to but I decided not to do so because I was out last night and am gonna be out tomorrow, Monday and a few times during the coming week) so why does staying in make me feel like I have

a) no friends?

and

b) no social life?

Does anyone else have this strange thing in their minds where, however much they go out the rest of the time, they feel wrong about staying in on a Saturday night?
