Japanese brush painting to an audience that included visitors from Japan,she was confused to see that many of her Japanese listeners had their eyes closed.Were they turned off because an American had the nerve to instruct Japanese in their own art form or they deliberately trying to signal their rejection of her?Obcamp later found out that her listeners were not being disrespectful.Japanese listeners sometimes close their eyes to enhance concentration.Her listeners were showing their respect for her by chewing on her words.Someday,you may be either a speaker or a listener in a situation involving people from other countries or members of a minority group in North America.Learning how different cultures signal respect can help you avoid misunderstandings.Here are some examples.
In the Deaf Culture of North American,many listeners show applause not by clapping their hands but by waving them in the air.In some cultures,both overseas and in some minority groups in North America,listeners are considered disrespectful if they look directly at the speaker.Respect is shown by looking in the general direction but avoiding direct eye contact.In some countries,whistling by listeners is asign of approval while in other countries it is a form of insult.

他们闭上眼睛是因为他们觉得一个美国人有胆量向他们教授他们自己的文化,还是因为他们是故意如此来表示反对呢?
第一段就是说Obcamp这个女的向日本人讲日本文化时,发现这些鬼子有时是闭起眼睛听的.她觉得是这些鬼子不屌她,因为她认为闭起眼睛听她讲是对她的不尊重.后来发现那些鬼子只是闭起眼睛为了更好地理解她的话.由此例子引出了不同文化的说者和听者表示尊敬的不同风俗.第二段就继续举例说北美的“聋文化”,对演讲者表示欢迎不会拍手,而是举起手甩.
之所以称为“聋文化”,就是他们不鼓掌.你想如果是一个聋子在台上讲,下面鼓掌他是听不到的,所以是用在空中挥动双手来表示欢迎.
后面就继续说在一些文化及北美的部分地区,直视演讲者眼睛是不尊重他的表现,表示尊重应该是看向演讲者的方向,但是要避开他的眼睛.另外,在一些国家,观众吹口哨表示赞同,而另一些国家这样做则表示侮辱.（貌似中国就是表示侮辱,这个就是所谓嘘声一片.）
