Several months ago I was involved in a car accident. That moment     my views on life.
All my life I had been waiting    I could get my driver’s     and my first car. When I    got my license and my dad brought the car to the house, I felt very    . From that day on, the most     thing in my life was that car. Every day I would get home and      what else I could do to make it better. My car was my    and joy and when I had fixed it up into “perfect” condition, I finally began to     it. Every time I got into my car I felt the greatest,     nothing could stop me, but one day I was     that just like any other person, I could be broken.

While driving down a main street I felt I was     the car. It was flying. When I     what was happening, the only thing I could do was protect my friends from being hurt badly.
After the accident I don't remember much, but I do remember the     I was in, not only physical but also the thought that the lives of others were     for a few seconds and I may have dropped them. The memory of that day will never     me. I learned that material things should     be the most important things in your life. I also learned that I need to appreciate the things and people around me.
