As I lie in my hotel room, it occurs to me that even a few hours in Indonesia have given me a very different impression from my first few weeks in Thailand. While I gather that Bangkok can get quite smoggy during some months, this has not been the case so far, and the contrast with Jakarta could not have been greater. I could tell the plane was nearing Indonesia’s capital not because I could see the city below, but because I could not; the rough contours of buildings only started emerging at closer range through a thick milky screen. We touched down at about quarter to six, and as I walked through the rather empty airport at six, the loudspeakers started playing the Muslim call to prayer. Of course, Islam is quite popular in Southern Thailand, but I have spent most of my time in Bangkok, which is decidedly Buddhist.
