This question makes me think of what my own (grown and married) sons had said at the dinner table one evening when they were visiting. One of them said "mom was just too over protective, she wouldn't let us out of her sight and it was embarrassing", and the others completely agreed with him. I just looked at my sons and said: Nothing bad happen to you guys, you were not molested, kidnapped or worse now were you, and I walked away smiling because you could hear a pin drop and I know they were absorbing what I said. :~)
SOOOO, I'm for being very "protective" no matter what, and no matter what anyone else says or thinks". It's better to be safe than sorry!
