Today I was having a PE lessons when 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’m wrong. We
can tell others our need for help and accept his help. Some day we can not help others in
return. In this way, we can get along to each other happily and peacefully.
