The power of positive thinking

Normally when I identify a problem with my car it is with dread that I take it to the garage. I know that it's going to be costly and that even if I get an estimate of the cost it'll be a 50 quid or more than I was expecting. This morning though I took my car in and as I was driving(through genuinely torrential rain that only seems to fall round where I live) I found myself whistling and smiling rather than dreading. I have no idea what had put me in such a positive frame of mind but it continued into the greasy garage office, through the rain to the station, on the train to work and up the hill through the light rain that falls everywhere else.

I just got a call. I stopped whistling and humming in an irritating fashion long enough to go 'uh huh' a few times and interpret the broad Yorkshire of the mechanic who said something along the lines of:"all checked, nothing really wrong at all, the steering and brakes are fine, it just needs tracking adjusted, we'll have it done in no time and you can pay us when you come in for your next service- it's hardly worth processing this one"

I'm a bit worried that if I stop being positive at any time before I pick the car up that I'll just be about to drive away when one of the mechanics will shout "hang on mate, I can see a really important and expensive thing hanging off the back of your car..."
