Camilla Chomp was a strange little girl. She liked to spend her time alone eating chocolate. Her parents were worried, so they took all the chocolate away. Camilla left her house to look for some chocolate. She found a small house full of bottles. Among the bottles, a blue bottle caught Camilla's eyes. It was full of chocolate. In the bottle there was also a card with the words "Change tears  into chocolate." Camilla was very excited. She ran out of the house with the bottle to look for someone crying. First, she met a little boy crying hard and collected his tears. The tears were quickly changed into chocolate. While Camilla was collecting the tears, she comforted the boy. Finally, the boy stopped crying and they had a good time together. Later, Camilla met a woman and an old man crying. The woman had broken some bowls. And the old man's dog had just died. Camilla collected their tears and made them happy again. Soon, Camilla knew that making people happy was much more important than finding chocolate. So she stopped collecting tears and began to help sad people. As a result, she had many friends and had a happy life. How many people did Camilla help before she stopped collecting tears?
