No TV on during meals here. It is a hardship for one 17 yo GS on Christmas Day. There is some bb game on he feels he can't miss. He always pushes the wrong button on the remote and I don't fix it until after dinner. Problem solved. I used to tell him it was a magic remote that respected Christmas dinner time, but I don't think he's fall for that now. Phones? Put it away or put it in the toilet. The parents let me get away with that though I feel they are the ones that should be saying it, but it's my house, so my rules if they don't.
