Mr. Mason was the only gym teacher I ever had. Until grade six, our regular teachers did the job, herding us all outside to play kickball or something, but in grade six they handed us off to Mr. Mason, who made us change into shorts—no matter the season—and run laps. In grade seven, he started teaching us all about sex and health. In grade eight, I asked him why the skin on my feet was peeling so much. He laughed and said I was probably going to die. And I decided not to take gym in grade nine.
