Cell phone etiquette!

The top five...hmmmm. My own like five most important in order would be... 1. Don't have a huge conversation with someone when you have a friend right next to you. Tell them you will call them back, it's disrespectable to your friend! 2.When your on the phone in public don't scream... Talk in a quiet tone...no one wants to hear the conversation your having 3. Don't talk about other people's private business in public. They don't want it out there more than likely. 4.DO NOT START TALKING ON YOUR PHONE IN THE MIDDLE OF A MOVIE! It's soooo annoying, and if it's that important take it out of the theater! 5. Don't text and drive, are you really trying to kill yourself and everyone around you?
