“The difference between friendship and love is how much you can hurt each other.”

“Do you know what the difference is between Friendship and Love? Friendship is the photograph, Love is the oil painting.”

“In romance or friendship, what's important is how much you love the other person."- Gackt”

“Love is the strongest emotion any creature can feel except for hate, but hate can't hurt you. Love, and trust, and friendship, and all the other emotions humans value so much, are the only emotions that can bring pain. Only love can break a heart into so many pieces. ”

“[A]s people are beginning to see that the sexes form in a certain sense a continuous group, so they are beginning to see that Love and Friendship which have been so often set apart from each other as things distinct are in reality closely related and shade imperceptibly into each other. Women are beginning to demand that Marriage shall mean Friendship as well as Passion; that a comrade-like Equality shall be included in the word Love; and it is recognised that from the one extreme of a 'Platonic' friendship (generally between persons of the same sex) up to the other extreme of passionate love (generally between persons of opposite sex) no hard and fast line can at any point be drawn effectively separating the different kinds of attachment. We know, in fact, of Friendships so romantic in sentiment that they verge into love; we know of Loves so intellectual and spiritual that they hardly dwell in the sphere of Passion.”

“Do you not know how bashful friendship is? Friends - comrades - do not look at each other. Friendship would be ashamed...”
