Delightful chap behind, as I slowed down to let someone cross the zebra on the super-cycle lane by St George's Circus, yelled 'look on your left, you cunt.'
I wished him a good day. Life is too short and the day too nice to waste time on that nonsense. That said, as the bloke next me said, 'miserable fucker, isn't he?' Anyway, if you're out there, I hope that shouting abuse at a random stranger somehow improved your day.
