It has not been a good day
Driving a carload of people to Owen's this evening, I reversed into his driveway, went a bit too close to a sharp bit sticking out of his gatepost, and tore a huge hole in one of my tyres.
This is, fortunately, what spare wheels are for. I'd never changed a wheel myself before, but it didn't turn out to be too difficult (apart from the fact that I somehow managed to break the handle off the wheel-changing tool holder while getting started!) and I've just got home in one piece. So tomorrow I suppose I'll have to go and get the tyre on the other wheel replaced; and in just a moment I'm going to go and have another try at cleaning the remains of the nasty oily gunk off my hands.
It hadn't been the best of days up until then, but that just pushed it over the line into One Of Those Days.
