A year or so ago, I was going to help a stranger jump-start his car. He didn't have jumper cables with him, but I keep a set in all of my motorized vehicles. I generally assume (often rightly so) that folks who don't own a pair of jumper cables do not know how to correctly utilize them. Whilst giving him the 15-second explanation on their use, he interrupted me. "Man... why black always gotta be NEGATIVE?" I took my jumper cables out of his hands, tossed them into the back of my car and drove off, leaving him with his hood (and his jaw) wide open. I haven't the time for crap like that.
