Here's how you know that you have a friend for life or just a passing acquaintance.

Aristotle says, "my friends, there are no friends". That seems like a contradiction in terms. How can you tell your friend that there are no friends? Well, that's the paradox of friendship, because you don't have to be friendly to have a friend. In fact, as Zizek says, one sign of friendship is that you can be rude to the your friend, you can insult them, and they'll see it as a sign of kinship, not a sign of being enemies.

A friend is somebody who knows you better than you know yourself. . A friend is somebody who doesn't judge you, but stands with you. A friend is somebody you don't always have to be friendly with. You're never polite to your friend. You're comfy with your friend.

A friend is not just a friend. A friend is another you.

Someone who knows you better than you know yourself is a friend. And yet a friend is somebody who allows you to be yourself in a way that you never could. A friend is someone who does not judge you but stands by your side. A friend is someone with whom you do not always have to be friendly. You are never polite to your homie. You're at ease with your homie.

A friend is more than just a friend. A friend is another you.
