It's not okay to do things to demean children.
Mike is at a kid's softball game just watching them play when Casey, a kid, comes up to bat.
Mike wants to say something to Casey.
Mike tells Casey that he's doing great, and he can get a hit, that Mike believes in him.
Mike tells Casey that he stinks, and he'll never get a hit because he's a tiny little loser.
Casey's confidence is boosted as this random stranger is acting like a fan and Casey feels like he's in the majors.
Casey is embarrassed and starts crying as he has no idea why the mean stranger is insulting him.
