The boys are fighting. The kids are imitating adult wrestlers. They are also dancing. Their brothers are wrestlers. The one boy told the other "I'm gonna get you because you knocked my sand castle over."
They are at a school playground so they might get in trouble. Their names are Denny and Danny. Denny is the one wearing a shirt. Charlie is behind them looking on. The guy in the middle is the big brother looking to break it up. He is also the referee. They both look like they are having fun.
Denny is going to be a leader when he grows up. They both look like they are willing to stand up for what they believe in. It's a draw!
The grown ups are watching so they must be having fun. They are also just being aggressive. They probably learned it from television. They appear to be in 1st or 2nd grade and have probably been in karate class. "I'm gonna get you" is how they feel. It feels natural for them to fight. Little boys push and shove each other all the time.
Their mothers are watching and cheering for their children. She is also trying to get them to quit. She tells them "Wait 'til your dad gets home" and "Go to your room."
