you'll shoot your eye out!
My mother always said, "You'll put
your eye out!"
My mother was not too keen on my having guns, so it was through intervention of my dad that I was able to get them. So I knew if I ever got careless and let my dad down, my shooting career would come to an end.
I just knew I had
to be careful. It must habve worked. I've been shooting over sixty years now, and have never had an accidental/negligent discharge.
