On my way to home yesterday afternoon,I happened to witness a traffic accident.When an old woman was crossed the road,she was knocked down by a boy riding bike.
The boy was such frightened that he stood still at the scene but didn't know what to do.
I quickly went up and saw the old woman lie on the ground,making crying because of pain.I stopped a taxi and told the driver that had happened.The driver drove them to the nearest hospital at once.To our relieve,we were told that the old woman wasn't injured seriously after she was examined carefully.The boy was deep grateful for our help.
