HB: You are right about having a daughter. and in your scenarios, it makes no difference. -- i'd still want the older, well-read, well-meaning (arguably) dude to keep his older hands to himself (and to his generation) and away from my daughter (or son).

Shadix: I know you find it hard to believe, but you won't be able to convince me... it's part of who I am, and gender has nothing to do with it. I'd feel the same even of a same-sex couple with such a deep age divide.
