Twice recently on a Saturday night, some kids went into our garage and messed up our car interiors, looking for something to steal. Subsequently I've been careful about my carlocks on Saturday nights. But a few weeks ago, as I laid my head on the pillow, I realized the car doors were unlocked. "Not to worry," I told myself, "it's windy, cold and rainy. No criminals tonight."
In fact I really believe that criminals would rather do their nasty-work in good weather. On average, they are probably less industrious than most people, or fewer of them would be criminals. It bothers me a little that I can sell this line to myself so easily, but, hey, maybe I'm right.
