For one thing, he added another bachelor's degree and then a graduate degree to the sheepskin that that college had given him. For another thing, he's now got pubic hair. (Ha, just kidding! I had that goin' on even before I finished college.) And for other things ... well, a lot has happened. Because it's been 20 years, right?
But here's one thing that I discovered: the more things change, the more they stay the same. When I was at reunion, I still recognized just about everyone. There weren't too many people who I saw and said, "Hey, I don't know that person," and then found out that I really did know that person. Sure, there were a few more paunches and a few heads sporting grey hair, but the people generally acted the same. It's kind of amazing, actually: the more things change, the more they stay the same.
