Digby is five years old and shits his pants nearly every day. Not accidentally, but spitefully, on purpose. He has been potty-trained for three years, uses the toilet when convenient, and is fully aware that this behavior is unacceptable. But still, he keeps doing it, and his mother keeps making me hand-wash his soiled underpants. “He just is so smart,” Stefany sighs as I carry a pair of briefs caked with poop into the laundry room. “He can’t stop whatever he’s doing to go. That’s what it is. He was so focused on his LEGO creation that he literally couldn’t pause to go to the bathroom.”
