One day, a boy named Tim went to the bookshelf to find a book. It was cold in the room, so he wore a big coat. Tim saw a big red book on the shelf. He wanted to read it.
Tim took the book and opened it. Inside, he found a word he did not know. The word was "reverse." He asked his mom, "What does 'reverse' mean?" His mom said, "It means to go back or change something."
Tim thought it would be fun to reverse the cold room. He said, "I want to reverse the cold!" But he did not know how to do it. He tried to say the word "reverse" many times, but nothing happened. The room stayed cold.
Tim felt sad and started to cry. He did not like the cold room and he could not change it. His mom tried to help, but the room stayed cold. In the end, Tim and his mom had to stay in the cold room with the big red book. They were not happy.
