    It seems that everyone is possible to be misunderstood for some reason. I am no exception. One day after school, I got on my bike and start heading home. I was just about to get out of the traffic jam outside our school while a woman stopped me, claim that my bike had scratched her car. I felt confused because that I clearly remembered that I was trying to avoid touching his car just now. Therefore, she insisted on blaming me and gradually rose her voice. Surrounded by a crowd of people, I got anxiously and desperately wanted this to be over. So I made a compromise.

    Never before in my life I dealt with such a thing, and I was apparently taken advantage of. Now I am aware that I should never give in as long as I am on the right side.
