Ok so if any of you have watched the OC then you will know what I am talking about. If you haven't I'm sorry. The Cohens and Ryan Atwood are a type of meso-system. They fall in this type of system because they are two different groups coming together. The Cohens are rich and live in a nice neighborhood while Ryan is poor and lives in a horrible neighborhood. The 2 micro-systems come together and form one meso-system.
