I went to my 10th. It was lame. The "speeches" turned out to be the old 'cool crowd' telling a bunch of inside jokes and jerking each other off. A bunch of us bailed early and went to a park and drank.
The one highlight was a "geek" from our class who got picked on a lot showing up, buffed up beyond belief, with a trophy wife, in a mercedes convertible.
Seems he made millions in the dot-com boom. The pair showed off their dancing skills (competitive ballroom dancing), shook a few hands and left after about 30 minutes.
