On the way to work this morning, a car pulled up next to me. I turned to look, and the man driving turned fully toward me and mouthed "I love you." Then he sped away, waving in the rear-view mirror.
At least, I think that's what he said. More likely it was "wash your car, dirty" or "stop putting your mascara on while you're driving." (For the record, I only do that at red lights.) Still strange.
