      Driving cars, trucks and motorcycles is an important part of our lives. We do it every day to get to

work, to school or to friends' houses.

      Driving can be very convenient, but can also cause many problems. Waiting in line at a red light, a

driver may get impatient and decide just to drive right through it. If another car is coming from the other

direction, there might be a terrible accident. Cutting another car off can make its driver angry, so that

driver cuts off someone else. Pretty soon everybody is angry, and impatient.
