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 his foot became worse. 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.
