Lily and Ben like to play with trains. They have a big box of trains and tracks. They make long and short trains. They make loops and bridges. They have fun.
One day, they find a new train in the box. It is green and shiny. It has a big funnel on top. It can make steam. Lily and Ben want to play with the green train.
"Please, can I have the green train?" Lily asks Ben.
"No, I want the green train!" Ben says.
They both pull on the green train. They do not share. They are not nice.
The green train does not like this. It does not want to be pulled. It wants to be played with nicely. It makes a loud noise. It makes a lot of steam. The steam is hot and wet. It makes Lily and Ben let go of the green train.
"Ow! That hurts!" Lily says.
"Ouch! That is not fun!" Ben says.
They look at the green train. It is still making steam. It looks angry. Lily and Ben feel sorry.
"Sorry, green train," Lily says.
"Sorry, green train," Ben says.
They decide to share the green train. They take turns to make it go. They make it go fast and slow. They make it go up and down. They make it happy. The green train makes less steam. It makes a happy noise.
Lily and Ben are happy too. They play with the green train and the other trains. They are nice. They have fun.
