Do you shave with an electric razor? Suppose your razor stopped working in the middle of a shave. What would you look like?
My razor has never broken in the middle of a shave, but for some reason, I worry. In order to minimize the risk, I try to shave symmetrically. I shave my right cheek, then my left cheek; my moustache; my right jaw, my left jaw; my chin...
If my silly fear ever materializes, my face will look like I tried to do something intentional to it.
