****This image expresses personal choice -- some spend their leisure time engaging with others, while some will spend it in an unconscious state. It is stronger than the other version of this scene, because it contrasts the sleeper with something else, in this case the pair talking on the left. As in my own pictures of a Beijing sleeper athttp://www.pbase.com/image/86310216 and a Xian sleeper athttp://www.pbase.com/image/31311555 , your image works because of the context your provide to your own Shanghai sleepers here.
