Once upon a time, there was a little girl named Lily. She loved to play with her blocks. She would stack them up high and be very proud of her tall towers. One day, her little brother, Tim, wanted to play with her blocks too.
Lily did not want to allow Tim to play with her blocks. She was afraid he would knock down her towers. This made Tim very sad. He just wanted to play with his big sister and have fun too.
Their mom saw the problem and had an idea. She gave Tim his own stack of blocks to play with. Lily and Tim both built their towers together. They were both proud of their stacks. Now, they could play together and be happy.
