A day's delay, as Joanna was ill in the night, keeps us in Bangkok where the mercury soared to 34C today, and you could cut the air pollution with a knife.
A knocking at my door at 4.30 am, heard above the whirr of the lurching ceiling fan (God, they are scarey things: I feel a scarcely resistable desire to put my hand up to its whirring) and the din of an antiquated air conditioning unit outside my window, could only be a maniac.
As there have been lots of wild noises in the corridor (we are staying in a budget hotel), I don't open. Renewed knocking at 5 am reveals itself to be David with news of Joanna's indisposition. He had been the earlier knocker too, but become embroiled with a drunken Belgian next door to me.
I devote the day to air-conditioned museums. I have spent the previous few days long-distance walking around town.
I have booked a flight home for 11 February. David and Joanna will travel on for a while beyond that. My thoughts begin to turn toward London.
