Since a serene disposition is valued, conflict and sudden displays of anger are eschewed in Thai culture. For these reasons, visitors should take care not to create conflict or to display anger. Disagreements or disputes should be handled with a smile and no attempt should be made to assign blame to another. In everyday life in Thailand, there is a strong emphasis on the concept of sanuk; the idea that life should be fun. Because of this, Thais can be quite playful at work and during day-to-day activities. Displaying positive emotions in social interactions is also important in Thai culture.
Often, Thais will deal with disagreements, minor mistakes, or misfortunes by using the phrase mai pen rai, translated as "it doesn't matter". The ubiquitous use of this phrase in Thailand reflects a disposition towards minimizing conflict, disagreements or complaints. A smile and the sentence "mai pen rai" indicates that the incident is not important and therefore there is no conflict or shame involved.
