Mary was a big and friendly elephant who would do tricks and perform for people to make them happy. One day, a man who was mean and wanted to hurt Mary made her angry, so she accidentally hurt him and he died. People were scared of Mary and thought that she could hurt more people, so they decided to kill her. This was very sad because Mary was not a bad elephant, she just got angry and made a mistake. It is important to treat animals with kindness and respect, and not to provoke them or make them angry.
