Once upon a time, there was a fireman named Tom. Tom was very careful when he did his job. He loved to help people and discover new things.
One day, Tom went to the park to play. He saw a big red ball and wanted to discover what was inside. He tried to be careful, but the ball rolled away and went into the street. Tom was sad and wanted his ball back.
Tom ran to get the ball, but he forgot to look both ways before crossing the street. A big car came and hit Tom. The careful fireman was hurt very badly. He could not help people or discover new things anymore. Everyone was very sad because Tom was not careful this time.
