Unbeknownst to Chang, his parents are playing a trick on him by presenting him with a wrapped bar of soap for his birthday. Chang opens the gift and, on seeing the bar of soap, looks over to his grandmother and hesitantly and softly says, "I wanted this soap, grandmother. Thank you!" Clearly, Chang's body language indicates his disappointment in the gift. What likely explains why Chang lied about his enthusiasm for the gift of soap?

a. The soap is the only gift Chang received.
b. Chang is not lying but likely enjoys soap.
c. Chang is a habitual liar.
d. By saying he wanted the soap, Chang is displaying the social norm of politeness.

Every society has certain tradition and norms which it follows. There are some norms which are specific to a specific society whereas there are other norms which are followed by every society. Politeness is a virtue or a norm which is followed by every society in the world. If people wouldn't be polite to one another then interaction of social beings on earth would be extremely difficult.

In the above example, Chang also showed politeness by thanking for a gift which he did not want.
