Agreement with 'Two Years in the Melting Pot'

Liu's rough experience dealing with American culture exactly illustrates basically what life is about for those living under a different culture circumstance. I agree with him and conclude that it is reasonable and understandable that foreigners are tend to stay with people who have the same culture background. Two main reasons are cultural gap and loneliness.
No matter how much time I have spent trying to be with American people in order to get inside the culture, the gap between people that have different culture background is still unlikely to be removable. Culture shock is everywhere. One same result can be resulted from different perspectives by people who have different culture background, because the culture in our mind has deeply influenced the way we are thinking and the way to judge what is right and tolerant and what is wrong and unacceptable. For example, when Liu was tempted to speak out that what the professor was teaching is not right, he received a response which was considered rude and offensive by him with Chinese culture background but normal and reasonable by Americans. Culture shocks apart and separate us from American and certainly result in that we Chinese like to be with other Chinese.
Loneliness is hard to overcome. For us, it seems to be true that living in a different culture is sometimes like living in another world. To be with people from my own country can make us feel warm. We are likely to become close brothers and sisters dealing with difficulties together.
Cultural gap and loneliness generate the distance from being adapted with a different culture and contributes that people from the same country like to stay together.
