The fog envelopes the city like a heavy blanket and blurs all edges. A short distance away the surrounding buildings disappear in the murk. There is a halo around the moon and around the streetlights and in the closest light droplets can be seen swirling like smoke. The faint swosh of a car comes towards me and I can see the beams of light sweeping the ground in front of it. Thursday night, no one is out and about except me, everything is dampenedd by the mist. Were it not for my infected eye this would actually be very enjoyable in a philosophical way.
