Perspectives in the Park is more than just a fictional book. It illustrates the use of judgments and perspectives that each of us see and use on a daily basis in our lives. Have you ever wondered what people do and what their real life entails? Your response is always "I bet he or she is _____________." Jack Gillen and Bobbi Klein have taken perspectives and assumptions to a new level. We have completed a sociology and psychology study that puts into perspective how you live your life and how assumptions can be detrimental to everything that you do (life, business, relationships, etc.). 1 Day in Chicago. 5 People. 10 Short Stories.
