DEAR ABBY: My 21-year-old grandson is a dramatic and arrogant know-it-all. My issue is that he’s disrespectful to me, especially in social situations. He’ll roll his eyes or flap his arms around as if I have two heads. He’s actually mean-spirited. I’m not sure how to handle it. Should I simply ignore him, or should I confront him with how I feel? — MISERABLE GRANDMA IN OHIO

DEAR GRANDMA: You should definitely tell him how you feel if you haven’t already done it. He’s acting like an overgrown adolescent. If his behavior continues, avoid him, if possible, as you would any other person who treats you with disrespect.

P.S. Also give serious consideration to “avoiding” him on his birthday, at Christmas, during graduation and any other gift-giving occasion.
