text: Imagine if you got hurt and there was no adult around to help you, you would automatically want to call someone with your cell phone. Its a lot faster to use then waiting for a teacher to come help you. If you were in serious pain and needed to go to the hospital, you would go straight to your phone and call 911. Lets say you forgot your homework or your lunch, you would want to call your parents and ask them to bring it to you at school instead of going to the office and calling. Its faster and easier to use your own cell phone.
