Important Etiquette Rules

These are five rules that I believe are most important on cell phone etiquette:
1.) Lower your voice when taking calls in public~No one wants to hear your conversation
2.) Avoid taking calls when having a face-to-face conversation~ It is very rude
3.) Avoid taking text messages when having a face-to-face conversation~ It is super rude
4.) Put your phone on silent or vibrate when in a movie theater or restaurant~ You could get kicked out and it is considered inproper actions
5.) Don't post pictures without the other person's permission~ It is the nice and responsible thing to do
