If so, do you do it for all of your friends or just some of them?
If only some of them, is it on purpose or just a matter of chance?
If you don't get one from a friend that did them for other people, are you hurt?
Sometimes I feel bad for not doing them, but I have over 100 people on my flist. I don't want people to feel slighted if they don't get one so I just don't do them at all.
