It is polite to share your toys
Nate and his friend Ryan are kindergartners, and it is time to play with toys.
Nate wants to play with a set of cars and ramps.
Nate gets the cars and ramps and gives some to Ryan, so they can play together.
Nate gets the cars and ramps and keeps them to himself, refusing to let Ryan play.
Nate and Ryan build an awesome set of ramps for the cars to run down, having a great time.
Ryan cries and complains to the teacher, who then scolds Nate for being selfish.
