事故(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.
