"I HAD TO GO to America for a while to give some talks. Going to America always does me good. It's where I'm from, after all. There's baseball on the TV, people are friendly and upbeat, they don't obsess about the weather except when there is weather worth obsessing about, you can have all the ice cubes you want. Above all, visiting America gives me perspective. Consider two small experiences I had upon arriving at a hotel in downtown Austin, Texas. When I checked in, the clerk needed to record my details, naturally enough, and asked for my home address. Our house doesn't have a street number, just a name, and I have found in the past that that is more deviance than an American computer can sometimes cope with, so I gave our London address. The girl typed in the building number and street name, then said: "City?" I replied: "London." "Can you spell that please?" I looked at her and saw that she wasn't joking. "L-O-N-D-O-N," I said. "Country?" "England." "Can you spell that?" I spelled England. She typed for a moment and said: "The computer won't accept England. Is that a real country?" I assured her it was. "Try Britain," I suggested. I spelled that, too--twice (we got the wrong number of T's the first time)--and the computer wouldn't take that either. So I suggested Great Britain, United Kingdom, UK, and GB, but those were all rejected, too. I couldn't think of anything else to suggest. "It'll take France," the girl said after a minute. "I beg your pardon?" "You can have 'London, France.' " "Seriously?" She nodded. "Well, why not?" So she typed "London, France," and the system was happy. I finished the check-in process and went with my bag and plastic room key to a bank of elevators a few paces away. When the elevator arrived, a young woman was in it already, which I thought a little strange because the elevator had come from one of the upper floors and now we were going back up there again. About five seconds into the ascent, she said to me in a suddenly alert tone: "Excuse me, was that the lobby back there?" "That big room with a check-in desk and revolving doors to the street? Why, yes, it was." "Shoot," she said and looked chagrined. Now I am not for a moment suggesting that these incidents typify Austin, Texas, or America generally or anything like that. But it did get me to thinking that our problems are more serious than I had supposed. When functioning adults can't identify London, England, or a hotel lobby, I think it is time to be concerned. This is clearly a global problem and it's spreading. I am not at all sure how we should tackle such a crisis, but on the basis of what we know so far, I would suggest, as a start, quarantining Texas."
