Once upon a time, there was a little girl named Sue. Sue loved her aunt. Her aunt was very nice. They liked to play together. One day, Sue's aunt came to visit her.
Sue's aunt wanted to teach Sue something new. She had a big bag with her. She opened the bag and took out a lemon. The lemon was yellow and round. Sue looked at the lemon and was curious.
Sue's aunt cut the lemon and gave a piece to Sue. She told Sue it was sour. Sue tasted the lemon. It was very sour, but Sue liked it. She smiled and said "thank you" to her aunt. They laughed and enjoyed the sour lemon together.
