i was walking away from a polluted urban stream lined by peppercorn trees or willows and into a fairly large and empty urban distribution centre car park. and although outside, and although i just walked out of a polluted urban stream, i’m carrying a purple helium-filled merchandise balloon from a store, holding it by the knot. and then i walk ‘into’ another ‘store’, but its all outdoors, in a car park, there are no products on display, no walls, no cash registers, just a single uniformed shop assistant. i get nervous because she will see me as i try to climb over the thief-proof exit, which is one of those electic detectors you see at the exits of media stores, but this one is also fitted with a 7ft. high pane of plexiglass blocking the gap between the two detectors (which i guess means no one may exit the store legitimately because all customers are theives?), and this person-sized transparent wall is surrounded by nothing, no other obstacle, its just there out in the open of the car park, blocking only the footpath. i try to climb it, but as i near the top i realise it is too precarious atop it to shunt myself over, there are no footholds, just smooth plastic. i know ill lose my balance and the single shop assistant will notice me if i struggle. so i ease myself down and explain i bought the purple helium-filled merchandise balloon from another outlet, and the woman escorts me away in some direction toward something else.
