Still teaching manners at the table

My wife says I'm old fashioned because I make sure we eat dinner together with phones put away and the kids use proper table manners. No elbows on the table, napkin in your lap, chew with your mouth closed. My daughter complained last week that none of her friends have to do this stuff. I told her that's exactly why she needs to. These little things matter because they show respect for the people around you. Been doing this for years and I'm not stopping now.
