In Shanghai, we stayed with Mary's niece Anja and husband Julian. Walking about one day I noticed Anja's red shoes next to a stone pavement marker and thought them worthy of a photo. After that I kept looking down and became distracted by the variation of manhole covers that we came across. That became a subject for a photo essay. I think a lot of bystanders thought it odd, but in Hong Kong we visited with Mary's nephew Philip and his wife Alex. She thought it perfectly normal. She is also an architect, so we think it's an architect thing.
