The three major principles that guide relationship formation can be applied to many situations, and are even featured in American popular culture. Romance is a component of many movie plots, including the 2008 romantic comedy Forgetting Sarah Marshall. The two characters that fall in love, Peter and Rachel, display all three major principles. First, the two are in close proximity because Rachel works at the front desk of the hotel that Peter is staying at, so they see each other every day while Peter is in Hawaii. Second, Rachel and Peter display similarity and have things in common. They were both in serious relationships and got cheated on, and they both are at transition points in their lives. Third, they display reciprocity towards each other in the form of favors to maintain equity in their relationship. Rachel allows Peter to stay in a very expensive suite at the hotel free of charge, and Peter removes an embarrassing picture of Rachel from the men's bathroom at a bar, even though the bartender brutally beats him up for taking it down.
The three principles, proximity, similarity, and reciprocity, show that falling in love with someone is far from random. Although physical attractiveness may play a role in the probability of two people wanting to get to know each other, there's probably no such thing as love at first sight. In order for a relationship to develop successfully, the three major principles need to be acted upon to some degree.
I think that your blog is a great application of proximity, similarity and reciprocity. It allows us to make connections to movies we have seen and than relate that to our life experiences. It is a lot easier to understand the concepts when you put them into the context that you did. It is interesting to know that finding a significant other is not random at all, there are underlying things that take part in the process that we didn't notice until psychology class.
