Girls

One of the things I pride myself on is my balance of relationships with men and women. Generally, this balance leads me to understand relationships between guys and other girls. One of the things that I've noticed is so different between the sexes are females' uncanny ability to analyze every single interaction that they have with a love interest. What is it that moves us to take on such a time-consuming endeavor? One of my housemates bores or annoys me constantly about her attempts at relationships so I need a justification of this behavior so I can accept it easier. I don't need the answer to, just an answer. Since Biology is so much fun, I'm using it for my femanalyzing hypothesis:

Mr. Butler taught me that put in the simplest of scientific concept, the purpose of life is to reproduce. As we all know, human females carry a huge majority of the responsibility of the reproductive process and the extended length of motherhood requires them to be extremely invested in their young. Ladies know that having an equally invested man helping raise the children is the best case scenario, but men just want to biologically plant as many seeds in as many places as possible. Therefore, women have always had to discern the nature of a love interest before mating and I guess we've evolved into focusing our brains' analytical power on figuring out how invested a guy would be in raising your offspring.
