Don't worry, that will pass when you understand how Americans live and talk.
Some people say that language is culture, and in many ways it's true.
American culture, like the American version of the English language, will seem very strange to you. How much you enjoy your time in America depends, in part, on how well you understand the culture. You came to America for the education, and part of that is learning how people live in a different country from your own. All Rights Reserved.
