Carol is a young girl who is only 15 years old, and lives with her parents. Next door there is a boy called Melvin who is the same age as Carol and happens to be Carol's best friend and the only person that Carol trusted in the whole world because he never waved in their friendship. He was very helpful and friendly person to Carol than anyone else had ever been. Carol could not even trust her own parents as she had no confidence in them except in Melvin who later she realized was not a trustworthy friend as she had always thought. One day Carol felt extremely paranoid about monsters who were watching her. She tried to control the problem but realized she needed to know who was watching her. So one day she confides to Melvin about it and went ahead to find out who the monster was. She went to a museum where they were many paintings that had meanings which were helpful to her. She knew she would find her mystery through the paintings. When she visited the museum again she was taken underground where the makers of the paintings worked from and she began to learn more about paintings. Without her expectation, she was waved away to the world of watchers who were very secretive. And in the process she discovered that Melvin his best friend was an agent of the watchers and he was the monster who kept watching her. She confronts Melvin about it and feels unhappy that it was his friend who betrayed her. The story of Carol teaches us not to put all our eggs in one basket. Carol's trust was all in Melvin and she could disclose anything to Melvin only to realize later that Melvin was not the kind of friend she thought he is. It encourages us to choose our friends carefully and not disclose every single thing about ourselves to our friends.
