This afternoon I was having a PE lesson while I fell down and hurt my foot. I was in greatly pain at that moment, but I tried to act as if nothing has happened until the class was over. Though I had difficulty walk back to my classroom, I still didn't tell anyone but even refused the offer of help of my classmates. As result, the hurt in my foot became bad. Now I know I am wrong. We can tell others our need for help and accept his help. Some day we can help others in return for. In this way, we can get along to each other happily and peacefully.
