From the Observer's Book

Now that The Small Object of Desire has been and got herself a new job I'm back on the public transport commute. I'd forgotten what a trial my fellow commuters are…

The Power Walker: Usually dressed like an extra from the touring production of"Bonfire of the Vanities," they're determined to stride out in a ruthlessly straight line, taking no prisoners in the battle for that stretch of pavement.

The Hypnotised Diagonalists: Earphones glued in to keep out the world, eyes fixed on the mobile device in their hand as they walk straight across you without warning as you try to cross that busy road where the pedestrian crossing's been out of action since last Summer.

Mrs. Overalls: Usually men, Mrs. Overalls dither about in shop doorways, train doorways, tram doorways, in fact any narrow passageway you may need to get through in a hurry. Their motto is: "I'm not actually going anywhere, and by God! neither are you."

The Metropolitan Cyclist: Expensive bike, speedos, hi-vis spectacles and streamlined cycling helmet, the Metropolitan Cyclist has the spatial awareness Ida seven-year-old and the arrogance of a ham actor playing a Spanish grandee in a remake of "Zorro."

TrishanEm: Two or three women functioning as one loud series of announcements about the sexual inadequacies of friends' boyfriends; bulletins about the doings of That Bitch; and Daily Mail headlines. Usually looking like the Black & White Minstrel Show had run out of burnt cork and had to resort to gravy browning.
