After three indolent days, I was ready to drop out - shave the head, get a floppy monk's bag, sit by the river, selling sheets of paper embedded with marigolds. But I was having a love affair with a great river, so I flew on south to Pakse, where the Mekong starts to widen. Here I boarded the Vat Phou, a steel barge converted into an airy houseboat with shiny rosewood decks, 12 comfortable cabins, elegant cane furniture and smiling staff in silk.
