I saw an accident happening on my way to home this afternoon. A girl was crossing the street on a zebra crossing while a young man drove a motorbike towards her. The young man saw the girl and tried to stop, and he drove too fast to stop. He hit the girl and fell off her motorbike. The girl was badly hurt and couldn’t move.
