Charlie is pouring his drinking milk into his cereal...
Mommy: Charles Patrick, stop that right now. You know you are not allowed to pour things!
Charlie: Whimper... Charlie strains to pout, but ends up looking more like a marionette doll
Mommy: Charlie, that will not work. Pouting is not going to get you your way. You are smarter than that.
Charlie: But... He manages to get his lower lip out into a real pout for a second.
Mommy: Copying the pouty face. Buddy, honestly, would this face change your mind and make you give me anything I wanted?
Charlie: Straight-faced. That's not going to work. I'm done.
Charlie pushes back from the table to go play and Mommy laughs.
