text: If there was a problem where we needed to be picked up because it is raining and we do not have an umbrella, we would not be able to if we did not have our cell phones. Another example would be if a friend or classmate needed a ride home. And when parents pick up their children, their is always a long line at the front of the school, so they call them to let them know they will be parked by the curb two blocks down the street.
