Today, as usual, I was humming a tune and riding my bicycle fast. I went to Dongyu primary school to play table tennis. When I got there, I pushed my bike into the corridor leading to the classroom, and I also put my bike on an oblique side, which was conducive to rushing out quickly, because I had to play until 8:30. Who didn't want to go home and take a bath early. Because of the trouble, it wasn't locked up. Then I went upstairs to play ping-pong. At 8:30, I ran downstairs in a hurry and pushed my bicycle forward. However, the bicycle refused to go. I felt the lock in the dark and found that it was locked. Then I went to touch the key chain, but I did not find the key. I was sweating like a soybean and turned on the light to find it carefully But I didn't find it. I was so anxious that I was about to cry. I thought it was the one who talked about Zhuo haosuo, so I was going to beat him up tomorrow. But I never found the key chain. She went home in a huff and was ready to ask her mother to pry the lock and replace it with a new one.

    On the next day, my mother asked me to go with her. We searched the stairs earnestly. At this time, I found a note in the corner: "little classmate, I locked your lock. This must make you very worried. I apologize to you. I did this because there is a paint union riding your bicycle away. The key is on the paper. Please lock the lock next time He (she) I was deeply moved, I must learn from big brother or sister, that kind of spirit of helping others. In fact, there are many such people in the society, because their world is more beautiful.

    The key came back again, which was unexpected and gratifying to me. More importantly, I learned to be careful and learn to help others.
