Lily and Ben are playing with blocks. They want to make a big tower. They have many blocks of different colors and shapes. They stack them on top of each other. They are happy. But then, Lily sees a block that she likes more. It is red and round. It is in the middle of the tower. She wants to have it. She tries to remove it with her hand. But the tower is not stable. It wobbles and falls down. The blocks scatter on the floor. Lily and Ben are sad. "Look what you did!" Ben says. He is angry. "You ruined our tower!" "I'm sorry, Ben," Lily says. She is sorry. "I just wanted the red block. It is my favorite." "Well, you can't have it," Ben says. He is still angry. "It is mine. I found it first." He starts to search for the red block among the other blocks. He looks here and there. But he can't find it. He is frustrated. Lily sees the red block. It is under the sofa. She crawls to get it. She is happy. She holds it in her hand. She thinks it is pretty. She sees Ben. He is still searching. He is still angry. She feels bad. She wants to make him happy. She has an idea. She goes to Ben. She shows him the red block. She says, "Ben, I found the red block. It was under the sofa. Do you want it?" Ben sees the red block. He is surprised. He is happy. He says, "Yes, I want it. Thank you, Lily. You are nice." He takes the red block. He looks at it. He says, "It is a nice block. But you know what? I think it is too big for our tower. It doesn't fit." He gives the red block back to Lily. He says, "You can have it, Lily. It is your favorite. I have another block. It is blue and square. It fits better." He shows her the blue block. He says, "Do you want to help me make the tower again?" Lily sees the blue block. She says, "Yes, I want to help you. The blue block is nice too." She takes the blue block. She smiles. She says, "Thank you, Ben. You are nice too." They hug. They are happy. They start to make the tower again. They use the blocks that fit. They have fun.
