Not I, you can get away with anything when you're old.  I'd act senile but really not be oh and deaf.  That way I could always know what people were saying about me and everyone else.  Then when I've had enouh I kill them and claim the cats did it.  "THOSE CRAZY CATS KILLED MY ENTIRE FAMILY MR. BOBBY!".  The cops, ie Mr. Bobby, would just laugh and laugh..."that's our grandpa...."....the world would never know. MAWHAHAHHAHAHA
