Sometimes I believe in Karma

(Walking down to the swimming pool).

Idiot in rear of car: [Incoherent abuse]
Me: ??

A minute later… thanks to the glorious intervention of the traffic lights at a complicated junction:

Me: I'm terribly sorry, I didn't catch what you said to me.
IinC: [Dives down to hide]
Me: You definitely tried to communicate with me. Could you repeat it?
IinC: mumblemumblemumble
Me: Are we acquainted?
IinC: [Now sitting up, staring fixedly at unwavering traffic light] ………
Me: Only, your tone sounded distinctly pejorative and I wondered why you would do something like that.

Lights change. Car zooms off. Idiot in Car leans out and repeats whatever it was. Too late. I was already happier, sure that for a brief moment, the worm had turned.
