This could sound a bit like “The Princess and the Pea.” Yesterday, confined to my apartment with the flu, I looked outside my window and down 8 floors. There, much to my wonderment, but not total surprise, I saw a car driving on the sidewalk, and slowly inching in upon a woman pushing an older gentleman in a wheel chair. This is one of those scenes that makes living in this city so interesting and comic. No one was hurt or startled by this. It’s all part of the strange ballet that is Beijing traffic, aka, the Probability Field.
