The one class I dont really talk in is my government class because I dont like anything related to government and politics and I have no interest in talking about the Texas and US government. Plus I hardly know how the system works. I think one other class that makes me awkward is a media commentary class where they go on and on talking about the different TV shows (a lot which I am not aware of) and they also talk about the American people and their views (being a non American I am at lack of words when I am faced with this topic). so I guess we could say interest and knowledge of the topic are 2 important factors that might make an international student speechless in class.
