I've beeen travelling into London from Epping for the past few weeks now. I'd not seen any trolleys, except at supermarkets, wwhich is where you'd expect to find them.
And one morning, at the far end of the car park I leave my car in, was a trolley. Just starring at me, taunting me. I resisted the temptation to take a picture of it.
Later that day, 11 hours later in fact, I returned. And the trolley had moved within feet of my car. And I felt trapped by my own obsession.
This trolley sat here, in the position pictured, waiting for me, every day for a week.
