I was late leaving work on Friday evening, and my car was all steamed up on that murky November night. I know I should have started the engine and let it run to clear all my windows before leaving, but I was bursting for a wee, and wanted to get home quickly, so I just mopped the mist from a big circle in the front windscreen, before I set off into the fog. Why my demisters chose not to function properly that night, I have no idea. All I know is that I couldn’t see a thing properly. I turned down the car radio. I always think that if you can’t hear, you won’t be able to see properly either. That’s probably a ridiculous conclusion to draw, but that’s how it seems to me.
