A cell phone is helpful; it is one of the most important communication devices. For example, if you want to talk with somebody for an important reason, you can. One time I was coming back from work at 10 o' clock at night, and I had a problem in my car. It wouldn't move. I was scared to go into a store to call my brother because I didn't know the places there. I thought it could be dangerous. That night, I found out that owning a cell phone is important.
Cell phones are extremely popular among teenagers. One problem is that they talk on them while they're driving. At 16 to 18 years old, they're very active. Sometimes some of them aren't careful and drive too fast. Talking on a cell phone while driving at high speed is very dangerous.. They shouldn't drive and talk on the phone at the same time because they can't control the car and may cause accidents.
