Aristotle and friendship

I was brushing up on my ancient greek philosophy and I was thinking about what Aristotle said about friendship. One thing that strikes me is that he thinks the highest level of friendship is not possible between males and females, which caused me to examine my own friendships. I have formed a strong bond with my cousin. The first time I ever laughed out loud was at Ethan. It was Dec. 1, 2007. Anyway, back to Aristotle. Aristotle would examine what the basis of our friendship is: one might like another because he is good, or because he is useful, or because he is pleasant. Depending on why I like Ethan defines the type of friendship we have. The highest level of friendship and the most perfect is the virtuous friendship. I think it is easier for us to achieve such a " perfect" relationship because we are young, and it is easy for us to be virtuous, so it seems less complex. However, it IS more complex than I have time to delve into here. . .
