• DON'T make or take calls when you’re in a confined space such as a bus, train, restaurant, doctor’s waiting room or anyplace where those around you will be forced to listen.



• TURN YOUR PHONE OFF completely during public performances such as concerts, lectures, movies, your child’s piano recital, plays, and yes, even sports events. And if you forget, don’t pretend that’s not your pocket ringing, singing or imitating the mating call of some wild animal. Turn the phone off immediately and under no circumstances answer it.
  
  
• DON'T dial and drive. Don’t text and drive. And if you’re going to talk and drive, be honest about whether or not you can really give the road your full attention even while using a hands-free head set.



• DON’T YELL. Background noise where you are is what causes you to raise your voice on a cell phone. Look around; if people are giving you the hairy eyeball, lower your voice, call back later or take the conversation elsewhere.
