I admire the gall of the Chinese woman who rode full pelt at me on her bicycle, ringing her bell loudly, as though I would step off the pavement into the road, so that she could continue riding along. I kept my face deliberately blank as I stared at her, and she favoured me with what I presume was her dirtiest look as she dismounted, pushed her bike past me along the road, and then got back on to the pavement before continuing to cycle.

If I had known enough words in a language she understood to explain to her that riding her bicycle on the pavement was wrong, I would have told some pretty rude things, including where she and her bicycle could go.
