Are culture differences that bad? - 20120530

One of my classmates went to UK a few years ago. We all thought that he must be comfortable  since he got a good job. However, he gave up his job and came back to China in 2011. He told us that he was not used to the "culture difference". After breaking up with his girlfriend, he realized that people in western countries might think in some different ways, that's the main reasons of misunderstandings.

Cannot love defeat all difficulties?
That's a sad topic.
