I'm with woodboats. Passive aggression works neither on my motorbikes, not my pedal bikes. It's a losing proposition. Besides, with my luck, I'd ride over my own tacks on the way home (with more dire consequences). Just be thankful you're on you're bike, and not stuck that truck behind you. But who knows, maybe she was trying to get a closer look at the bike.... damn, why I am so optimistic all of a sudden?
