As much as I love living in San Francisco, some of the denizens of this beautiful city are a bit twisted. On the way home from dinner today, a group of guys were crossing the street on the far side of the intersection while I was stopped at a stop sign. One of them saw the car and started making very exuberant "fisting" gestures and then pointing to my car. I gave them an appropriate gestural response as I whooshed past them in stealth mode. I hope, for their sake, that they know the difference. In San Francisco, asking for the wrong one of those two things could lead to a very different experience than he had expected.
