The other day, while motoring along, I saw a female cyclist who's chain was thrown off the sprocket. She picked up the chain with her fingers and got it on the chainring, then looked at her greasy hand. She was trying to wipe her hand on a light pole when I pulled over with a moistened towlette for her (yes sometimes guys have them). She was very startled by me at first, then realized that I was up to no harm. She thanked me kindly and said that she was pedaling to a job interview, and that dirty hands wouldn't do.

I didn't mention that I was a cyclist in disguise, so maybe now she has an elevated opinion of motorists (or men in general).
