Once upon a time, there was a little girl named Lily. She loved to play in the field behind her house. One day, her mom said, "Lily, if you behave today, we can go play in the field later." Lily was very excited and promised to be good. They went to the store and Lily saw a toy she really wanted. She asked her mom if she could have it, but her mom said no. Lily started to cry and throw a tantrum. Her mom said, "Lily, if you don't behave, we won't be able to play in the field later." Lily knew she had to stop crying and be good if she wanted to play in the field. She took a deep breath and calmed down. Later that day, they went to the field and had so much fun playing together. They ran around and played hide and seek. Lily was happy she behaved and got to play in the field with her mom. From that day on, Lily remembered that if she behaved, she could have fun in the field with her mom. She knew it was important to be good and not throw tantrums, or else she might not get to play in the field again.
