Gathering my thoughts on the way to the airport, to catch the flight back to Delhi, I was selecting the sensations for which I will remember Thailand. In the rush of sights and tastes and smells stood out one loud sound &lsquohoye&rsquo. A call that rose quickly to a crescendo and then tapered off. A quick spike of excitement, levelling into gentle appreciation. It is the sound of a crowd appreciating a fine punch or a kick.
