Whenever I have lunch with my best friend she always has her phone on the table, face up. She knows I think this is rude but she says she has to be available for her kids. Am I the inconsiderate one or is she?

How many times have we been to restaurants where people at the same table are not looking at each other but down at their phone screens. It looks ridiculous but they don't notice because they are so busy there's no time to look up!
