It began as many changes do: Gradual and nearly imperceptible. As November arrived, there was a slight change in the humidity, accompanied by breezes that moved in during the night. Daylight comes a few minutes later each morning, and nighttime creeps in a bit earlier each evening, throwing off routines by the slightest measure. It then is apparent that rain has not fallen for a few days, then a week, then two. Nasal passages are suddenly dry, and the air conditioning gives way to fans, then to fans shut off in the middle of the night while half asleep we reach to throw covers over us. I notice that the shower heating knob has slowly been turned from the blue cool range of August to the red warm indicator as December approaches. I now must water the outdoor plants, and I take fewer showers, as there is not a constant sticky film of perspiration on my skin. More students come to school wearing sweaters or jackets, and Thai workers wear knit caps and down vests. Thankfully, the cool season has arrived--This morning is was 19 C (66 F), unusual, but welcome.
