Wow. Scary stuff.

If he only had one sexual charge on his record, I would think maybe there was a chance it wasn't what it seemed. There is a registered sex offender down the block from me. His girlfriend's parents pressed charges when they found out they were having sex, after letting them date for a year. He was 18, she was 16. Incredibly sad and unfair, IMO. But your neighbor doesn't seem to fit that pattern at all.

I'd be very cautious, friendly but not too friendly. Don't want the guy thinking you're buddies and dropping over, but you sure don't want to make him an enemy right off the bat, either.

And, honestly, how many of us have a criminal on our block right now, and don't know it? I'd say almost all of us.
