It's especially the high school thing... loads of people my age are all over "friends reunited" and organising reunions already... it's only been five years! My memory of high school is that I met some people there who have become lifelong friends, but I don't miss the actual time we spent together then - I much prefer the way we spend time together now. In fact my overwhelming mental impression is that I was a lazy brat, I hated the city, and most of my class pissed me the hell off.... ;)
