I graduated 5 years ago from high school. I've kept in touch with a couple of them on a consistent basis, but for the most part it's on really random occasions (such as birthdays, parties, get-togethers, etc). Why not more often? It's because we're all working, most of them full-time. And we've kinda...moved on with our own lives, I guess. A couple of them are already married; one is engaged. I don't really relate the same way with them like I used to in high school.
