What do you think about culture shock? I have a Vietnamese friend and a American friend. I thought it was great if I introduced them together. But it was not simple like my thought. Their thoughts were different with other one. My Vietnamese friend thought that when she wanted to practice English with some one and helped them for improving Vietnamese, they were friend. But My American friend thought that they were not friend, they were only partner. That's problem. So, they had a hot disputation and blocked other one. I think it's just misunderstading. You can see their definition of "friend" is different. My Vietnamese friend thought that she needed to know some simple information about "friend" who could help her and whom her could help. But My American friend thought that they could practice without any personal question althought they were simple personal questions. Do you think that's culture shock?
