Levels of friendship

[Katullus]

Today I've read something cool about friendship I'd like to share with you guys. According to Aristotle, there are three levels of it.

The first level is considered by him to be vulgar. It's when the friendship is based on mutual advantage. Like two squash players that "befriend" only to be able to play.

The second level is considered to be less vulgar. It's when it's baseed on mutual enjoyment, like when people gather to have a nice time or to socially vibe.

The third level is the only one not considered vulgar. it's when both friends inspire themselves in the other. It's a friendship based on mutual inspiration.
