I have to say I'm midline to all y'all, I carry my phone everywhere, because I had a bad enough incident when my car broke down in the middle of a big road trip that having a phone turned it from a disaster into just a nuisance. And my family has a culture that you're not really supposed to just randomly ignore calls. If you're really busy such as in a theater show, or unreachable underground in the subway, or even in a conversation with someone important, sure, but not "ho hum I don't feel like talking to you" isn't a good idea for me.
