DISPLAYS OF RESPECT
To avoid confrontation or disrespect, many will not vocalize disagreement. Instead of relaying negative communication, people may not answer a question.
It is disrespectful to touch another person's head. Only an elder can touch the head of a child. When getting a praise, people usually smile instead of saying "thank you". A smile is like a silent "thank you". Most people are very modest and deflect praise.
Insults to elders or ancestors are very serious and often lead to severed social ties.
