Today 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 worse. Now I know I was 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.
