An Accident
One sunny afternoon, when I was merrily riding home, I heard "Help! Help!". I rode to the riverside and found a boy of about five in the river struggling. I jumped into the water, swam to the boy and dragged him to the river bank. the boy said he was trying to catch a fish near the river bank and carelessly fell into the water. I asked him where his home was and sent him home. "Thank you very much!" the boy’s parents said, when I left his home. Though I got home late that afternoon, I was very happy.
