oooh, i'm scared

Last night, while waiting for pie to appear, I looked over and saw a dog in the next car. Look, I exclaimed to the GE, what a cute dog! GE looked over, made a motion as if to wave or something at the dog, and the dog immediately raised its lips at him in a fierce snarl. Hand down, mouth back to dog smile, hand up, dog snarl. We had way too much fun with this for a while, then another car pulled up and parked. As the family walked past the dog's car, the dog snarled, then proceeded to go crazy barking and jumping at them (at the window, actually). The family got a big kick out of the dog. The pie arrived, we showed A. the hand-raising=dog-snarling trick, then we started to back out of our parking spot. The dog kept its head in the exact same position, following us only with its creepy crazy eyes...
