An airplane flight can be unpleasant enough with that very un-fresh recycled air. Add someone's exposed smelly feet into the mix, and it only gets worse.
This 4-year-old kid wasn't having any of it when the passenger behind him put her exposed foot up through the opening between the seat in the wall, protruding into his space. He just called her out, first to the camera describing those "stinky feet," then going back to where the appendage was poking through, asking her "Why do you have your feet behind me?"
I LOVE this kid!!!
