Cycling home yesterday evening, the traffic along my normal route was logjammed. So, being a good cyclist I took a shortcut that only cyclists can use and then wove around a number of stacked buses to get almost to the front by the traffic lights. When I got there, another cyclist was waiting for the lights to go green. I made an observation about the logjam to him, he looked at me to reply - and it turned out to be a chap that I used to work with 23 years ago - !
