Thais aren’t so friendly that they will go out of their way to talk to anyone who walks by. They do respect your privacy, but if you are interacting with them, then you are welcomed in like part of the family.
You instantly feel good around them and all your guards drop because you know all they bring to the table is acceptance, warmth and love. On my recent trip to Thailand, I laughed a lot with the Thais and I realized just why they are so awesome.
