Smiling Thai
As time passes you will meet the real Thai, an authentic culture with precious norms and values as displayed (amongst others) by the Buddhism. One of these values is their open and welcoming spirit towards foreigners visiting Thailand. Therefore they will always try to help you when you have some difficulties understanding Thai or finding your way. There are exceptions, some vendors try to convince you to buy one of their goods in an aggressive way but do look a little further and you will see that the myth is true, Thai are smiling all the time.
