I will defer to Aristotle on this one, except I would not define anything below “true friendship” as “friendship” at all. Friends are the ones that can go years without talking and still pick up like it was yesterday, that would do anything you ask and you the same, that you want to see just because you want to see them and for no other reason. My friends are varied and many don’t like each other, but they all share an honesty and prickly nature that I find endearing.
