I was wandering around central Auckland a couple of weeks ago when I stepped in a pile of spit that had emanated from a young Chinese student squatting beside a lamp-post.
"Yuk," I thought.
Then I remembered visiting a Chinese hospital where liberal use was being made of a spittoon. In their culture, I recalled, it was acceptable to spit both outdoors and in.
The hospital visit occurred during an 11-year Asian OE in which I learned that the Western preference for blowing noses into pieces of paper was considered to be pretty gross in some cultures.
In Auckland, I was struck by how much Queen St had changed demographically during the past decade. For half an hour or so I played "spot the Pakeha", and the results were enlightening.
