Whilst I am grateful my wife and I are the same age this isn't just about foreigners. My Thai neighbour in his 70s married and girl of 19 with the blessing of both families. She is now 24 and looks older than her years but he was true to his word and bought her a car and she has her own business all paid for by him. No one is kidding themselves this is nothing more than a transactional relationship that is of benefit of both parties.
