Tim and Lily are twins. They like to play with blocks. They make big stacks of blocks and knock them down. They laugh and clap.
One day, they see a new box of blocks in the living room. They run to the box and open it. The blocks are different colors and shapes. They are very happy.
They start to make new stacks of blocks. Tim makes a red stack and Lily makes a blue stack. They want to see who can make the highest stack.
They put more and more blocks on their stacks. The stacks get taller and taller. They are very proud.
But then, Tim's stack falls down. The blocks make a loud noise. Tim is sad. He cries.
Lily hears Tim cry. She looks at his stack. She sees that it is broken. She feels sorry for Tim.
She walks to Tim and hugs him. She says, "Don't cry, Tim. It's OK. We can make a new stack together. I will help you."
Tim stops crying. He looks at Lily. He smiles. He says, "Thank you, Lily. You are a good sister. I will help you too."
They walk to the box and pick up some blocks. They make a new stack together. The stack is yellow and green. It is very pretty.
They are happy again. They hug each other. They say, "We love blocks. We love each other."
