I've never been to one. I still talk to the few people from high school I wanted to talk to when I was in high school regularly. I have no desire to see the people I didn't want to see then again.
I hear you. I said the same exact thing. I still see or keep in touch with everyone I want to, except, what I've realized is that there are a bunch of people that were only acquaintances or just kind-of friends that I'm actually interested in seeing again. But, I would agree that with most people, I could just pick up a phone and say, "hey."
I agree. It gives you a chance to meet up with people that you'd like to see again, but are no longer close enough to that a phone call is acceptable, or really have anything in common with except that you're going to the same reunion. Throughout the years you forget the people in-between your good friends and your "enemies", and I think those are the people that are interesting to meet at reunions.
