text: After school as a student I may need to walk home or take the bus alone which is dangerous because no one knows exactly where I am but God, they only know where I'm supposed to be. If my father expects me home from school at 6o'clock and I'm not home because my bus was delayed by 10 minutes I could call him instead of having him search every bus stop before my house. Cell phones help us make our lives easier and more convenient.
