My SIL from my first marriage.  She had no concept of how to act around anything dangerous.  For example (and this is my favorite) I was felling a tree in my late MIL's yard.  The idiot SIL came up behind me and goosed me in the ribs and screamed "Boo" to her a big joke but I had a 60' tree about to fall and a running chainsaw in my hands.  I hate to think what she would do with a weapon.  Heck we could just drop her in the Middle East unarmed and in a week she would have accidentally killed half the population thus ending the war.
