Chapter 11 focuses on the emotions and feelings that humans encounter throughout their everyday lives. What I found most interesting was how different cultures have different views on certain emotional and human behaviors. This applies to everything from the most casual of encounters, like handshakes, to the more intimate, like kissing. In the United States, kissing someone on the hand or cheek is considered, by most, to be an act of friendship and fondness. But in India, those same acts are considered scandalous. For example, Richard Gere was guilty of committing this Indian scandal with Indian actress, Shilpa Shetty, at an AIDS awareness rally in India. You can read more about this story at this website.
Another major social human behavior that is viewed differently in cultures in personal space or the proximity of others to your being. In America, we typically have about 12 feet of space for public speaking, 4-12 feet for average conversations, 2-4 feet for conversations among people with whom we have a close relationship with, and 0-2 feet for intimate actions. These culturally appropriate distances differ from country to country. For more on cultural differences of personal space, go to this website.
The reasoning behind these cultural differences is just what each culture's norms are. There's obviously not one set universal rule for social behavior. Different people accept different customs regarding social activities. I personally think that these behaviors that are considered acceptable in certain cultures are also tested on individual basis. Just because someone lives within a culture, doesn't mean they have to be comfortable with that culture's beliefs regarding social situations. I believe it should be decided on more of a person-to-person basis instead of a culture-to-culture. Cultures can have their norms, but the people within those cultures should be able to deviate from them as they see fit.
