If you’re an uncle or aunt, it’s your duty to be the cool uncle or aunt. Take your nephews or nieces out to McDonald’s, to the arcade, or wherever their hearts desire. They already get enough grief from their parents’ constant “nos” and “maybe next times.”
But this uncle felt that he had to set a good example for his nephew since, according to his sister, the little guy followed whatever the uncle did. This included not eating junk food in front of the kid. But the kid felt that both he and his uncle had to undergo a secret popsicle-eating mission out of mom’s sight. And the best place to do it was the bathroom.
