By October our dorm pod bathroom smelled permanently warm and sour, and nobody could figure out why. My roommate Eli was huge, shy, always showering at 3 a.m. One night I woke to a wet stamping noise and cracked the bathroom door. Through the steam I saw him awkwardly crushing something into the drain with his bare heel. He looked horrified when he noticed me watching. Later he admitted the shared toilet was too small for him to sit on safely, so after clogging it once he’d started using the shower instead. I should’ve been disgusted, but the secrecy and embarrassment made it strangely intimate.
