A couple of years ago I was at the stop line with a red traffic light. To my left was a big red double-decker bus. I was turning right, he was going straight ahead. It was December, cold, and pouring with rain in London. An ambulance, with siren blaring came round the corner so I shuffled the bike over to my left to make more road space for it. I came close to losing my balance during my lateral shuffle and reached out to steady myself against the bus.....and met air. My hand went straight in through the open driver's window and hit his arm.
Profuse apologies followed, but he took my assault in good humour.
"It must be miserable to be on a bike in this weather"
"No, it's great fun actually, but I would have said the same thing eighteen months ago."
He have gave me a big grin and wished me well as the lights changed.
It was a rather wonderful "ships in the night" exchange.
