This is a bad way to look at it because I'm kind of on the opposite side of this. I'm the kind of person who rarely reaches out, largely because I don't usually have much to say. I only reach out if I feel I do have something to say. I have friends I haven't talked to in weeks, months and in some cases even years for no other reason than I have nothing to talk about with them.
That and I also feel like I'm being annoying sometimes, so I get a bit nervous about reaching out to people sometimes.
