I hate to agree but I think you are right. You just don't know what a
person's intentions are these days. My wife, who is a corporate
executive, used to mentor underprivileged children and found it very
satisfying. Eventually her company lawyers told her it had to stop.
Seems that these kids needed mentoring because their parents were
usually losers and all they had to do was say that their kid said that
the (mentor) "touched" them to hit a jackpot. (aka Michael Jackson;
"you pay me X amount and I won't sue). Even if completely exonerated
your life is ruined and you can't even counter sue because they don't
have anything.
I could see taking some stranger for a ride and finding out later that
they were irreversibly "traumatized" or something. Am I being too
paranoid here or what?
