This... is my clear hero.
This young dude - he knows his classmate is scared. She's afraid her mommy won't come to get her after naptime, at around Four. Clearly seeing that she's perplexed, this young man makes a solemn pledge of honor to his young classmate...
... to protect and defend her. And he reassures her that mom will indeed come unto her to pick her up.
It's amazing. It's honor. He's got it.
