Theories are for Weirdos

So here I am sitting at home doing my readings for my Communication Theory class, thinking whoever wrote this book should be shot. WHO CARES ABOUT THEORIES OF COMMUNICATION? ARE PEOPLE HONESTLY GOING TO, IN THE MDDLE OF A CONVERSATION SAY; "Hmmmmm, yes this is and example of objective communication, and it is semiotic something something because of this and this pointless idea." WHAT PURPOSE DOES THE STUDY OF COMMUNICATING SERVE? WHEN WILL I EVER NEED TO KNOW THE DIFFERENCE BETWEEN SOCIO-CULTURAL AND SOCIO-PSYCHOLOGICAL COMMUNICATION? ARGGGHHHHHH! I thought the end of useless classes came with the end of high school. Oh how naive I am, this is just the beginning. Stupid class.
