When I was a kid, we took a lot of black-and-white pictures. One of my cousins locked himself in the dark bathroom to develop the film. We all stood eagerly next to the bathroom door, waiting for the negative. Then, one of the kids walked over to the light switch, turned it on for a second, and then turned it off. Disappointed, my cousin walked out of the bathroom with the ruined negative. I asked—actually, I yelled at the other kid—why he flipped the switch, and he calmly replied, “Me? You did it.” To this day, I still can’t understand why he did it or what his motivation was.
