Have you guys seen the movie THE BOYS ARE BACK? Highly recommended. At one point the six-year-old skipped thru the airport shirtless announcing,"I've got nipples!" It reminded me of an incident last summer when I was out hiking barefoot and shirtless, and a family group approached. The (approximately) five-year-old boy pulled up his shirt and smiled, as though saying, "See, I've got nipples too!"
