Farangs aren't expected to wai, but I thought it would be nice to learn, so I had a local demonstrate.

So far, though, it hasn't been necessary to learn. All the signs are in
English and virtually everyone I've encountered speaks English. The one exception was the cab driver who drove me from the airport. Finding the hostel was a treat.
As thankful as I am that communication isn't an issue, I'm vaguely disappointed that in Bangkok, of all cities, it's so easy. The exotic mystique of the city is diminished somewhat every time I walk by a Burger King or Subway or 7-11. I'm not upset to see Starbucks, though. I went almost two months without a decent cup of coffee.
