I've always wanted to do this. I have friends that I havnt spoken to in a while who I would really like to stay in more regular contact with but it's hard once we don't have a social reason to see each other on anymore. Every time I think about doing this I worry that it's way too self indulgent. I'm already a bit, see very, self absorbed at times and I think this would come off as a extension of that. Am I just paranoid?
