Something that I have lost

Something that I have lost in my life is wallet. In 3 years ago, after finished the school, I lost my wallet on my way home. When I knew the fact losting my wallet, I was very disappointed. In my wallet, there were lots of money, certification, and other invaluable cards. Therefore, I went to the outside in order to seek my wallet. Suddenly, I thought if I leave it in the bus. My guess is right. I am not happy until seeking my wallet. After I was barely regain my wallet, I was able to take breath. Also, I felt that significance of wallet.
