voices from the past

So I got an email out of the blue from someone I knew in college -- one of my friends from my first two years, when I was a member of one of the more conservative Christian groups on campus. He and his wife and two kids are moving to the area (more or less) soon, and he wants to get together to catch up on old times.

These things are really awkward. I made such a deliberate effort to become a new person during the last year or so of college, and the couple of years after that, that it's hard to meet with people who knew me before that period. They don't really know who I am now, and I often don't feel like explaining it.

Not sure how I'll reply...
