You know how inside a jacket pocket there are sometimes washing instructions on a flap of cloth? I wore a new jacket when I went to Düsseldorf last month and it had just such a set of instructions. My driving licence had got behind them, so when I felt around inside I missed it. It was only after much systematic memory-searching that I noticed I hadn't taken the driving licence out of the pocket, so had a more thorough search.
Damn! Damn it! My new licence expires after 10 years and I have to get a replacement, but my paper one has no expiry date and I could have used it indefinitely (or until I was guilty of a driving offence requiring an endorsement).
Now, I'm going to have to cut up my old licence and send it back to the DVLA.
I KNEW I'd find the old one. I just knew it.
