When I'm on the computer, what pisses ME off is when the phone is on the other side of the house, and someone who ISN'T busy RIGHT next to it DOESN'T GET it. So I have to walk to the other side of the house because people are yelling at ME to get it. I always just put it back where I am because there's a phone charger right next to me anyhow.
Moral: Buy a good-sized batch (baker's dozen to be specific) of phones.
