Tom and Lily are playing with blocks. They have many blocks of different shapes and colors. They like to build towers and houses with them.
"Look, I made a big tower!" Tom says. He shows Lily his tower of red and blue blocks. It is very tall and has a circle on top.
"Wow, that is nice!" Lily says. She likes Tom's tower, but she wants to make something different. She has a yellow and green block in her hand. It is not a circle, it is a square.
"I want to put this on your tower," Lily says. She tries to put the square on the circle, but it does not fit. It falls down and makes a loud noise.
"Hey, don't do that!" Tom says. He is angry. He does not want Lily to ruin his tower. He pushes Lily away and grabs the square.
"No, this is mine!" Lily says. She is sad. She wants to play with Tom, but he does not share. She pulls the square and tries to take it back.
They both pull and tug on the block. They do not see that their tower is shaking. It is about to fall.
"Stop, stop!" a voice says. It is Mom. She sees the children fighting and the tower wobbling. She runs to them and catches the tower before it crashes.
"Tom, Lily, what are you doing?" Mom says. She is not happy. She does not like to see them fight. She puts the tower on the floor and looks at them.
"Sorry, Mom," Tom and Lily say. They feel bad. They know they were wrong.
"Can you say sorry to each other?" Mom says. She wants them to be nice and make up.
"Sorry, Tom," Lily says. She gives him the square. She does not need it. She can find another block.
"Sorry, Lily," Tom says. He gives her the circle. He does not mind. He can use another block.
They hug and smile. They are friends again.
"Good, now can you play nicely?" Mom says. She is glad. She likes to see them happy.
"Yes, Mom," Tom and Lily say. They nod and look at their blocks.
They have an idea. They can make something together. They can use the circle and the square and the other blocks. They can make an open house. They can put the circle on the door and the square on the window. They can invite Mom to see their house.
They start to build. They are having fun. They are playing with blocks.
