Dear Prudence,
My adult daughter, grandson, and I live together. Her boyfriend of six months is very quiet around the family. I know little about him. When he comes to our house, he never greets me or uses my name. It’s as if he pretends I don’t exist. This is my idea of bad manners. I’m educated and friendly. My other kids’ friends don’t behave like this ever. Help.
