I've been a member of my high school reunion committee for our past two reunions. You might be very surprised...people really do grow up, mature, and change. At my reunions I ended up having fun with women who had been bullying toward me when i was in school years ago. There really are lots of surprises at reunions, most of them good! And honestly, there is not much comparing. Everyone had grown older, everyone has had his/her share of tough times. I think it's important not to decide what your reunion will be like before you attend it.
