In the ever popular movie, Bridesmaids, the main character Annie meets a cop by the last name Rhodes, who she eventually falls in love with by the end of the movie. In the book there are three major principles that guide relationships, and each of these can be spotted in Annie and Rhodes' relationship. The first of which is proximity, they may have met because Annie was driving recklessly but they ended up hanging out again and seeing each other a lot because Rhodes lived right down the road from her. If she hadn't lived in his area, they would never have met again and wouldn't have ended up falling in love. The second principle is similarity, in the book is says "we are attracted to people that are similar to us". Annie and Rhodes are both fairly equal in attractiveness, they both enjoy humor, and seem to have a lot in common with what they like to do. The last principle is reciprocity, the rule of give and take. We tend to feel obligated to give what we get and maintain equity in a relationship. Annie tells Rhodes a lot of deep hearted information about her relationship with her best friend and how Helen is ruining it. Rhodes tries to tap into Annie's baking world when he goes to buy her all the baking supplies one morning. In the end, Annie and Rhodes end up together like the movie had foreshadowed in the beginning.
The three principles that guide relationships can be seen in many other ways throughout the movie and many other movies as well. Can you think of more examples for Bridesmaids? Or is there another movie that comes to mind?
