a The first point I'd like to address is when not to use your phone. It's polite ID to switch off your phone or turn off the sound when you're in class or in a meeting. If you get an important cal you should ask for permission to leave the room and then don't talk for too long 15 Furthermore, for comversations that need more time, it is best to ask the person to call back at a more convenient time. cell phones can also cause you to neglect the people you are with ifnd it really annoying when my friends constantly check their messages on their phone in fact. I want to tell them to turn off the cell phone and enjoy my company
