I am a horrible shot - at a "family day" at my FIL's gun club I took 6 shots with a .22 at a target - pretty close (20 feet?) - not one hit.
My sister in law is quite the marks (wo?)man. I'm sure she could be a sniper if she was the military type.
That's why our dogs are protection trained and I sleep with a sword under my bed (plus I know which "decorative" swords are sharp and which ones aren't).
