Most graffiti isn't art

It seems that Banksy, London's most famed street, wall and pavement artist has been unmasked as a former public school, middle income, middle aged bloke called Robin.
As he doesn't live anywhere nearby, we can't look forward to selling off bits of our new Wembley town centre to bemused American collectors
We have our fair share of graffiti scribblers and provided it is not on their own private property most people don't care about it.
Brent Council does care however and will remove any obscene scrawl within 24 hours of it being reported to them.
My problem is, most of the rubbish written on street furniture is small and thus is passed virtually unobserved by the authorities.
Unfortunately, none of our local 'artists' have any aptitude at drawing real images they just miss-use our alphabet.
Also irritating is the fact that most of the writing is unintelligible and even though I do not read nor write all of the 63 common foreign languages spoken in Brent, I can swear that the writing is not in any one of them.
It is a lot like trying to comprehend the meaning of the keys on a keyboard, if just read out aloud from left to right - or even from right to left, but I've been informed, QWERTY is now in the Oxford English Dictionary as an acronym for Typewriter.
The best bit of graffiti I have seen was actually a computer generated image of the White Cliffs of Dover, with the words, "GO HOME - WE'RE FULL" scrawled along them.
I complained to one of the regulars at the Windermere pub about some idiot who had scribbled all over the bus timetable outside the building.
"If you end up standing around waiting for a late bus," he advised me sagely, "even you might be tempted to vent your anger on the signpost."
