It's hard living together with other people, and unfortunately there is hardly any other option other then becoming a complete hermit. Sartre proposes that life is hell because we must depend on other people. Even when we are economically independent, we rely on other peoples' perception of us. We have a need to be seen as "good people" - as decent, pretty, worthy individuals. While the play makes a good point, I felt it was quite unsophisticated and one-sided. A must-read for people who are weary of society, though.
