People of more means just seem to be more attached to their phones, bluetooth in ear, can't live without them, lol. They have all of those features, and 24 hour accessibility for co-workers, church workers, friends, you name it. It's hard to dial it back when you're so used to responding instantly to that email or text chime... I'm retraining myself to not drop everything and respond to the phone whenever it makes a noise. It's not healthy to be ruled by that tiny object, lol.
People are so dominated that no matter who they're in the room with, they will interrupt them to talk on the phone with someone else. The phone conversation doesn't even have to be more important. Even if the roles were switched and the person on the phone was in the room, they'd interrupt them to talk to the person on the phone. That makes absolutely no sense, but I know people like this.
