At the traffic lights by the pedestrian crossing on York Road near Waterloo station.
Other cyclist: "Loads of twats on the road today isn't there."
Me: "What? Like that cab driver by St Thomas's? He only beeped you because you swerved out to overtake the cyclist in front without signaling or looking behind you, you almost swerved into *his* path, he wasn't passing you closely as he was completely in the other lane, I was behind watching you both. Then you pull in front1 of me at the lights rather than queuing behind me, then you jump those lights by 5 seconds or so2, then you jump the lights on York Road which were clearly going to change before you stamped on the pedals, they'd been red for 3 seconds when you went through. And then, after all of that, you moan at a fellow cyclist because you think that everyone else on the roads is a twat? I've only seen one real twat on the roads this morning so far..."
Him: "..."
1. I passed him whilst he was calling the cabbie names.
2. Lucky for him, otherwise he'd have held me up and I'd have been delving deep into the large economy bag of stab.
