Embarrassing Moment

I can still remember the moment which was the most embarrassing time of my life. On the morning, I went to school by bike as usual. When I arrived the crossroad beside the school, I stopped and took my helmet off my head. However, a teacher came and said, " Why do you wear no helmet? " As a result, I reached the helmet and tried to put it back. Suddenly, the traffic light turned green so I pushed my bike across the street. Meanwhile, the bike started to fall because one of my hand was holding the helmet. Then, the bike lead me to fell with it on the crossroad in everyone's sight. I quickly stood up, bowed to the crowd, and I rushed away. I'm sure that everyone will be amused at my funny action that day.
