Well, here goes! Be aware that this section will change, almost by the hour, as I myself learn about Thai culture!
Thai culture is intrinsically rooted in its religion - Buddhism - and also its history. Both are deeply linked, but the overwhelming impression of the writer, is that Thai culture is based largely upon respect. Respect for the King, the religion, the family and in particular for elders!
Thai culture is very, very different to that which is called culture in the west! The 'middle way' is seen as the norm - no extremes. It is a way of life that avoids - frowns - on confrontation and displays of anger.
By nature, the Thais are kind, accommodating people, often willing to share what little they have - sometimes with complete strangers. By western standards, they are very relaxed about everyday life. Until you get used to it - and it would be wise to do so - you may find the haphazard treatment of such things as punctuality a little annoying. There is no rush in Thailand - unless you are in a taxi or Tuk-Tuk! Central to the Thai way of life is the short saying "Mai pen rai" (It's all right - never mind - No problem - etc!) So, if (when) your meal arrives a little late, don't worry, it will happen, have another drink. "Mai pen rai!" It's a great way of life once you get used to it. Embrace Thai culture and enjoy life!
The Family in Thai Culture
The family, elders and respect are all ingrained into the Thai way of life. Sons and daughters still see it as their 'duty' to care for - both emotionally and financially - for their parents and other close relatives if needed. If parents are wealthy, then this is not the case. This is basically a big 'Thank You Mom and Dad' for bringing me into the world and looking after me. It is not unusual for Thai working kids to go without in order to maintain their parents.
