It is one of the blessings of old friends that you can afford to be stupid with them.
Ralph Waldo Emerson
One of the most beautiful qualities of true friendship is to understand and to be understood.
Lucius Annaeus Seneca
Things are never quite as scary when you've got a best friend.
False friendship, like the ivy, decays and ruins the walls it embraces; but true friendship gives new life and animation to the object it supports.
Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.
