A quick story, even though I don't remember the exact quotes anymore:
I was riding my motorcycle to smegs on saturday, and I stopped at a light. I heard a "toot-toot", and saw a guy in the car next to me tapping on his horn. When I looked over, he gave me an enthusiastic thumbs-up.
I returned the gesture, with a smile, then he rolled down his window. I flipped up my visor. He said to me, "It's great!"
I smiled and patted my motorcycle. "Thanks! It's a pretty bike, isn't it?"
"It's great," he said again. "A girl on a motorcycle. That's hot."
I laughed and thanked him again. We exchanged another thumbs-up gesture, then I waved and rode away.
Fortunately I managed to not stall or do anything else stupid while he was watching. Don't want to ruin his good opinion!
