Etiquette: In interpersonal relationships, most Laotians are sincere and courteous. The meeting etiquette most frequently used by Laotians in social activities is Namaste, but they also use handshakes sometimes in foreign exchanges or in social situations where young people are in the majority. However, the vast majority of women are still accustomed to Namaste. Laotian women are mostly respectful and submissive in social settings. Under normal circumstances, they will not walk across in front of the guests. When delivering items to guests, they usually squat down, and sometimes even kneel in front of the guests.
There’s a traditional blessing ceremony in Laos -- Su Khwan, which involves in a wide range of activities, such as welcoming or seeing off guests, weddings, holidays and festivals, going out for travel, etc. The main function of Su Khwan is to tie the soul, drive out evil, and gather blessings. After the ceremony, it is best to let it fall off on its own, or at least wear it for three days, thus it will be effective. When the Laotian people give you a Su Khwan ceremony, please don't forget to do Namaste to them on the spot.
In general, Laotians call each other as relatives, or by their names with friendly or respectful address terms, like, "Tan" which means "Mr.", “Long” which means "Grandpa", “Ba” which means “Grandma", “Ao” which means "Uncle", “Na” which means “Aunt”, “Ai” which means “Brother” and so on.
