I’m trudging back from the park, feeling tired and for some reason dejected by the clammy cold breeze that’s whipping off the pavement into my threadbare old jumper. A bloke in army fatigues heads down the road towards me, at a fair old clip. He’s on one of those self balancing motorized unicycle things. As he zips past me I see he’s holding a can of extra strong lager and talking on the phone in Russian. He takes a nifty left turn, sips from his can and carries on the conversation. He’s a metaphor. Heading north towards Finsbury Park.Though it might have been Polish.
