discourse communities

I was very interested in the Wikipedia definition that stated, "Most people move within and between different discourse communities every day." I bet in any given day I move between 5-6 different discourse communities. I speak and act differently in class when talking to instructors than I would at my home with my roomates. I also speak and communicate differently with my boyfriend than I would with just a male friend. At work, I communicate with clients and my students much different than I would associate with anyone at college. I think it unique that an individual can move so freely between discourse communities without even realizing it.
