Once upon a time, there was a little boy named Tim. He lived in a small house with his mom, dad, and baby sister. Tim's room was upstairs, right next to his sister's room. He loved to play with his toys and read books in his room.
One day, Tim's mom asked him to behave while she went to the store. She told him to be a good boy and not make a mess. Tim promised to be good and started to play with his toys. But then, he saw a bitter lemon on the table. It looked so yummy, so he took a big bite. "Yuck!" he said, making a funny face.
Tim decided to go upstairs and play with his sister. They played nicely and behaved just like their mom asked them to. When their mom came home, she was happy to see that they were behaving well. She gave them both a big hug and a sweet treat for being such good kids. And Tim learned that behaving well made his mom happy and proud of him.
