Tomorrow, my wife returns from a trip to North Carolina, and it wouldn’t do to pick her up at the airport in a filthy car. Météo France predicted clear skies for Saturday, but a very unstable situation with a non-negligible chance of rain for today. During my lunch hour, I thought things were just fine, so I let the machine at the BP station remove the dirt and mud from several days of hideous weather from my Passat. I was on my way back to the office when clouds rolled in out of nowhere; I modified my itinerary, parked the car in its garage... and went back to work in my wife’s Polo (hey, it hadn’t just been washed, after all). Naturally, the sun is now out in all its glory, and there’s not a single cloud in sight. Murphy’s law strikes again...
