What do you do when someone you know wants to Facebook "friend-you," and you do not want to be friends?

Child rearing and the NYTimes

Have I become an old "fuddy duddy" for thinking it is important to teach children to respect them selves and one another? Why do we ask pre-school aged children "why" questions when they misbehave? Are they really capable of articulating their motives at 4 years old!

Guests

Is it rude to wish house guests would leave after they have stayed with you for over two weeks? Fortunately, you haven't been asked to give them the grand tour of the city, but gee I need some privacy, solitude and quiet. Is this a Six-Oh trait? Have I become a curmudgeon? Anti-social?
