I agree wholeheartedly, the more connected people claim to be because of their phones the less connected they actual are to those physical proximity. My rule is no phones at the table during a meal at home. I have taught my son that when we are eating out the same rule applies, no phones at the table.
It's a good practice to have no phones on table during meal since most of the time we are on our phone. It also helps to connect with each other better.
