text: Now i will also give one more freak example of why i think number one is the best. So you are in gym and someone trips you and you fall and break your leg. So now the school has to call the parents and tell them but wait the number got changed so you cant and don't have any way to contact the parent. billy bob phone has mommy's number. So if you when with policy two mom would never know but with policy one just cheek his book bag and get the phone and call.
