It was a gray blustery morning in Hackney Downs. A man with a dog stopped nearby and asked 'what's that mate?' to which I replied 'a radio antenna, I'm trying to catch the signal of a weather satellite'. He gave a thumbs up and said 'so it's a weather thing? a weather thing?' I nodded, and he walked off without further questions. I had apparently given a satisfactory answer. Yet I wondered what kind of 'weather thing' he was convinced I was operating.
