One can't complain. I have my friends. Someone spoke to me only yesterday. A farewell is necessary before you can meet again. And meeting again, after moments or lifetimes is certain for thoes who are friends.
Strangers are just friends waiting to happen.
To become a good man, one must have faithful friends, or outright enemies. Small people always do that, but the really great make you feel that you, too, can become great. Your friends will attend to that. Friendship is one mind in two bodies. And this becomes men's nature in the end.
