There are many advantages of being a head taller than everyone else. You don't, for instance, find yourself breathing into someone's armpit while travelling on the underground.
One problem, though, is the Chinese insistence on stopping in the middle of the road. If you are walking down a crowded street, you have to keep walking. If you really need to stop, you move to the side before doing so. Everyone knows this, surely!
It seems I'm completely out-of-sync with the Chinese walking style. I walk much faster and because I'm tall (and often have my head in the non-literary clouds) I don't notice much what goes on at ant level. When someone stops right in-front of me, I inevitably walk straight into them. This happens every day, sometimes more than once. It's frustrating.
