Crem, trust me, you'll be pleasantly surprised by how "normal" a lot of your ex-classmates will be. And quite a few will be having the same thoughts as you right now.
BTM - I've only been to the one reunion, mainly because it was a Big One (30 years on), was fairly close by, and there were a couple of people I really wanted to meet up with. It was interesting how people had changed - I certainly wasn't playing the same role that I played at school, and I came away with very different feelings towards people I wasn't at all close to back then.
MI - my parents eat plenty, but are continually taken by surprise by the amount their grandchildren consume, and always tend to under-cater .
I just realised it's Derby Day today. There are helicopters going over every five minutes and the village is full of Orange People.
And my time was.... (drumroll).... 38 minutes 16 seconds. Nearly 10 minutes behind DH, but not the slowest. Next time, I'll suggest the Park Run near Cheam, which is flat, apparently (err... did I just say "next time?"
).
