When on the highway
Someone honks and waves to you,
You must, in turn, wave.

Even when you don't know who they are.

While driving to work, I heard a honk and looked over to find a car which had met my pace. The driver grinned and waved, for all intents and purposes like someone who knew and recognized me before scooting on up the road. I had no idea who it was, but waved back dutifully. Either they were mistaken or I just didn't get a good look, but either way, I felt a bit ridiculous about the whole thing.
