I was sitting in the sunshine at the front of Green & Blue today sipping our delicious coffee and doing some work. A man walked past me, with one trouser leg rolled up to the knee, and the other worn in the usual manner. He was in all other ways unremarkable. Later this morning, I walked back to my car, and a different man walked past me, with one trouser leg rolled up to the knee, the other worn in the usual manner. He too was in all other ways unremarkable. As I arrived at my house, a third man walked past me, with one trouser leg rolled up to the knee - and you can guess the rest. Can anyone explain? Is this a football related gesture that I'm unaware of? Is the left knee flashers convention in town? I am suspicious that this is no mere coincidence.......
