What's Behind Door Number 2
Now it happens that I was the person in that first stall. And I thought to myself, "How rude! If I were her, I would have gone down to the last stall to do that!"
Being the kind of person who likes confirmation that I'm always right, I asked an authority later that evening: "Mallory, If you had to poo at school, and someone was already in the first stall, would you sit RIGHT BY THEM to do that, or go down to a stall as far away as you could?"
She answered that she would, indeed choose the stall inches away from the first occupant.
"WHY?" I asked, horrified – in my best "where did I go wrong in raising you?" tone of voice.
"Because if someone else walked in, they wouldn't know which one of us was taking the poo."
