I couldn't help thinking there was someone behind me all the way back from the City Campus. In the subway under the ring-road the echo of my footsteps sounded like someone stalking me. I followed the signpost to London Road leaving invisible footprints on the concrete slabs. Under surveillance the whole time. Tracked by the prying eyes of numberless CTV cameras - my mobile phone shouting out my geo-location to anyone who's interested. Anyone. Well, who exactly? Who cares? But reading this left its print on me, making me think that things run something like this: you could be anywhere, but you're always somewhere; anyone could find you, if they knew where to look - if they could be bothered in the first place.
