Aristotle and friends

According to the famous Greek philosopher Aristotle, there are three kinds of friendships.

He mentioned them in his book Nechomachian ethics.

There are friends of pleasure, those whose company you enjoy.

There are friends of benefit or utility. These are people, whom you interact with, for the sake of some mutual benefits.

Then there are friends of virtue, which you can say are true friends. Such friends are always rare.
