First came to Thailand in 1960 aged 20. Lived here permanently since 1983, apart from a spell of 6 years living and working in Taiwan. I would make only one observation, the nightlife was incomparably better/more fun in the 70s and 80s than anytime since. That is a fact, not an old man's rose-tinted memory. The relationship between foreigners and Thais was far friendlier in those days.
