I had a different post planned for today but with the way my day has been going this seems more appropriate.
Today I had not one but 2 flat tyres on my car. The original tyre that got punctured by a stone that was far pointier than it had any right to be, and the spare tyre from my boot that started leaking air as soon as it was fitted.
All of which left me with no option but to wait to be rescued by the lovely RAC.
So I offer up reason No. 1 for keeping a book in the car – so you have entertainment while waiting to be rescued!
