Grayson sat alone on the bus ride from school to home. He didn't want to talk to his friends or anybody else. They were talking about their homework for the weekend and they were happy because their parents would help them. But Grayson's parents were always busy.
When Grayson got home, Grandpa looked at him and said, "You look unhappy, Grayson.""It's my homework, Grandpa, Every student needs to ask a grown-up(成人) for help to make something together. The students need to write down how they make it. But I don't have anyone to help me,"Grayson said.
"How about me?" Grandpa asked.
Oh, his grandpa! Grayson soon sat at the table with Grandpa. They thought of many things to make: a kite, a lantern, a paper tiger... At last, they decided to make a robot out of old milk boxes. Grandpa even found some crayons to paint it. When they finished, the table was not tidy. But Grayson couldn't stop smiling(微笑).
"It's the best robot!"Grayson said. "Thank you, Grandpa! I had a lot of fun."
Grandpa said, "Me too. Maybe next time we can make something different." Grayson smiled again. He couldn't wait!
