My daughter nominated a friend I will call Mary for E-Hell status today.
Mary invited DD to dinner with her last night as DD was home for a visit and hadn't seen Mary for a while. DD said Mary spent the entire dinner Texting to other friends.
When DD said "Hey, we are having dinner together.." Friend Mary said "Well it is not like I am taking on the phone so it isn't rude."
As DD said to me "It is exactly as if she were talking on the phone."
So I think it is a slam dunk personally. Mary is in E-Hell.
