I went back a couple times while still in college. I even helped judge one of the debate tournaments when I was a sophomore or junior. It was soooo strange because half the school had been significantly renovated. It was great to see some teachers, but overall it was definitely strange. I actually have fond memories of older friends coming back to visit after they left for college. I enjoyed seeing them and they seemed to enjoy coming back. But that was also when they still knew people who were still in school. Now I think the only students I would know would be ones who were little kids in my moms classes, and to be honest, I don't want to see them as 17 year olds. They few who I have seen have ruined my image of them as a 7 year old, and have made me petrified of having children. I like JDs idea, though.
