This morning, my father took me to school by bike. I sat at the back of the bike, eating a banana. After I ate it up, I threw the skin onto the street randomly. No sooner had I done this than I realized that I had done something bad to our environment. And maybe someone would step on it and tumbleover. I must pick it up. Thinking of these, I asked father to stop. I jumped offthe bike and ran back to pick up the banana skin and threw it into a roadside dustbin. Seeing this, father praised me and I felt very happy.
In future I will protect the surroundings more consciously and think more about others.
