What is the appropriate behavior for a man or a woman in the midst of this world, where each person is clinging to his piece of debris? What's the proper salutation between people as they pass each other in this flood?
-- The Buddha

A house is about to be built here and, in typical Thai fashion, they arrange delivery of the most important bits first. Seems somehow logical that, as this is the rainy season, they want to keep dry. Therefore better get the tiles first! No bricks, concrete or even tools. Just the tiles.
I'll try to get a photo if they get the roof up without support.
