The nickname of Thailand is “Land of smiles” its true because Thai people always smile…It is as simple as that. You will see more smiling people here than anywhere in the world. 
Thai people are well-known as very hospitable, kind, inviting, friendly people full of life. At first, if you feel awkward or strange because they just smile to you even you have never met them before in your entire life and you are not used to it. You just give them a big nice smile back to them and you will feel better and you will get used to it eventually. It is a warm welcome for you……
A friend of mine, she had been to Thailand once. She was very impressed with all the smiling Thai people. At first, she also feelt funny with it and she was wondered if there was anything wrong with her or if she had done anything wrong wondering why people smiled at her. It was not just the first time that someone asked me about the ”smiling habits” of Thai people. That is why our home is called “Land of smiles”
Being a person who live abroad, I know we can all feel lonely or homesick sometimes. And if you are living in thailand and are feeling lonely try to get to know some local Thai’s and make friends with them. You would not feel as lonely anymore I’m sure. As a friend you get greated as you are a part of their family. As a foreigner you will recieve more attension and extra care. We Thais are very caring and nurturing people
Even though, Thai people are generally very nice and friendly there are some of Do & Don’t you should be aware of.
Hope you will have a wonderful time staying in Thailand and make some Thai friends.
Love
