It's wrong to pick on a fellow kid.
Tommy is playing in the school yard and notices another child, Tim, struggling to climb up the jungle gym.
Tommy wants to say something to Tim about his struggle.
Tommy walks over to Tim and offers support, telling him that he just needs to trust himself and keep climbing, that he can do it if he believes he can.
Tommy yells at Tim, calling him weak and making fun of his struggle to climb the jungle gym.
Tim feels a sense of strength and hope, and he continues to climb, while Tommy feels a sense of pride that he has helped his classmate accomplish a goal.
Tim feels embarrassed and stops trying to climb the jungle gym, and Tommy feels guilty about embarrassing him.
