Once upon a time, there was a girl named Sue. Sue was a regular girl, just like you. She had a friend named Tom. Tom had a big thumb. One day, they went to the park to play.
At the park, they saw a man. He made a sign with his hands. Sue and Tom did not know what the sign meant. They asked the man, "What is that sign?" The man said, "It is a sign for 'hello'."
Sue and Tom learned the sign and said 'hello' to the man. Then, something unexpected happened. Tom's big thumb started to glow! The man was surprised and said, "Your thumb is magic!" From that day on, Sue and Tom used the sign for 'hello' and Tom's magic thumb to make new friends.
