Im not so sure that they are really feeling much deep down inside.. I think that emotions, like rational thought have evolved less and differently in Thailand than in the West. Culturally and religiously they have no concept of Christian/universal love; only instinctive family love and Buddhist compassion which I would argue is different. In fact Buddhist non-attachment/Detachment exemplified by the Buddha himself abandoning his wife, child and family to seek his own salvation, is quite the opposite of love. More importantly Thais have not (yet) been bombarded by slushy romantic music, movies, stories, and advertising as we have been since the day we were born in the West. Who is to say what is right or preferable.
