They insisted that they were fine.
They were waiting with a group to cross the road at a set of pedestrian lights. Whole group just suddenly set off. I jammed brakes on, no time to do anything else. Impact on my arm, Big bang smash noise, I stopped within 10ft. Dreaded turning my head, expected to see someone prostrate on the road. No, she was upright, looking white-faced, held by her friends. Starbucks cup and ice scattered on road - that was what had made the noise.
Asked her if she was ok, she said yes. I was unconvinced - my arm had a bruise starting, it was so soon, she could have had a broken arm and not even felt it yet. So I waited and checked twice, her friends were talking to her and looking at her, they said she really was fine.
It frightened me. There was nothing I could have done differently; wasn't riding too fast for conditions (dry road, good visibility, doing about 15mph). They were stationary on side of road, looked to be waiting for the pedestrian light. I would have been further out from the kerb, except that some lads were starting to walk over from the right and I was concerned that some of them might speed up - so was giving them more room.
Really shook me up.
