OK, I didn't take this picture, but had I taken my camera delivering with me this morning I could have obtained evidence never mind a good photo.
A large plain white van was slowly (and I thought gingerly) trying to negotiate the narrowest part where parking is still allowed. I held back from walking past it because it was nearly on the pavement. Suddenly the was a loud crunch, the wing mirror of the parked car lost the will to live, and the van drove off pretending nothing had happened.
I strained to read the number plate, but without glasses it was very difficult. Even if I had been able to do so I suspect I would not have remembered it. I turned to an equally gob-smacked onlooker who couldn't either, and with no name on the side of the van there was nothing we could do but show our total exasperation with society and life in general.
I felt very inadequate and useless. Is there something I could/should have done...?
