Why so much about friends?

I was thinking today as i wrote my final, what the importance of friendship is? I mean obviously Aristotle thought they mattered quite a bit, since he wrote two books on them. But what does this mean for us today? It is my person belief that in our culture we don't put as much emphasis on friendship as we probably should. This could be why it seems odd to us his stipulations for a true friendship. But it does seem that everybody has at least has one true friend as aristotle says it. So maybe in our american culture we try to have too many friends? We are somewhat of people pleasers at the heart of it, and so we want more than one or two "true friends" but as Aristotle puts it that is basically impossible. It seems if we came to grips with that then we would be able to much better understand, and accept, what it is that Aristotle says about true friendship.
