Post elsewhere on this forum concerning a girlfriends' comments about the possibility of her boyfriends' mind snapping and the possibility of his killing her, (whew!) reminded me of a story from long back.
My wife commented to me once as I was cleaning some sixguns "If you lost your mind, I'd be in trouble."
I relayed this story to the range officer at the local range.
His response? "Bob, what makes her think you're in your right mind, now?"
