"We don't care. We don't have to. We're the phone company." (Lily Tomlin)
I remember when I was much younger, my siblings and I would all run to the phone as soon as it rang. Probably because even with the ringer at its lowest setting, it was still rather intrusive. If it happened during dinner, the phone would still be answered and whoever was calling would be asked to call back. We were nothing if not polite.
