While residents get paid for cooking dinner, each resident is assigned work to do each week. Living in a co-op has many benefits, not the least of which is learning how to live and work with complete strangers. Along with the many friendships that develop, a strong sense of tolerance and acceptance is fostered. The nature of the house is molded by the residents, becoming more or less social, athletic, or musical as desired. And since we do not subscribe to any preconceived notions as a house, we don't push people into roles they would rather not assume.
Students can become who they are, or who they want to be.
These two traits, of tolerance and individuality, would suggest a rather open and friendly house, a house that is open to anyone.
