sporty, if he's in MIL's room, aircon will be turned on to cool the room only ... but throughout, the fan is blowing at him directly. Even when he sleeps in an air con room ... not much diff too. But his sleeping hours also siao siao one ... like that day, when I was in NZ, apparently, one of the days, he stirred at 9 plus am, smile at hb then continue to sleep till 11am haha
