But the love which sometimes exists between friends is not (true) love, because it is subject to transmutation; this is merely fascination. As the breeze blows, the slender trees yield. If the wind is in the East the tree leans to the West, and if the wind turns to the West the tree leans to the East. This kind of love is originated by the accidental conditions of life. This is not love, it is merely acquaintanceship; it is subject to change.
