Don't zone out and lose concentration. I had rinsed and re-lathered and was on my second pass. Reaching over by head with my left hand, as I normally do, to pull up on my sideburn area stretching my whole right cheek area.

I was thinking about something else and didn't coordinate my right hand with my left. I had laid the edge of the razor on my cheek with slight pressure before I stretched rather then after. Wasn't a bad nick but the sting got my attention.
