I am adamant about one thing in particular. No phones at the dinner table. Being out to eat is tantamount to being at home. Regardless of where it is impolite to have a phone in between you and your supper plate not to mention you and your dining company. I believe that the very last meal of the day (exception being dessert of course) is meant to serve as a transition from the hustle-bustle of the day to the somnolence of the night. Face it, a phone in your face doesn't make for meaningful conversation. Chances are that phone has been in your face or in your fist for the majority of the day. Give it a rest, break some bread, and live a little.
