Dear Prudence,
My son (age 13) has a best friend who seldom, if ever, says, “Thank you.” It bothers me because I have tried to stress the importance of showing gratitude to my own son. His other friends are very good at saying thanks. He is not perfect, of course, but is learning this important manner. We don’t know the friend’s parents really well, but I was thinking I might mention it to Mom. My wife says we absolutely should not. What should I do?
