Why can't Friendship and Love be on the same side of coin? I feel, You can be friend and still Love him or her. I mean Love in a very broad sense. Loving is limitless. It can encompass all your actions. You can become an icon of Love, and become Godlike.
Now that I think deeply on it, what you say is astonishingly true, though it may seem otherwise. Friendship and affection can go together on the same face, as when an affection, say, such as an uncle's, is strong enough to seem like love, and in its way might even be termed, in some cases: love, but that love which isolates itself so as to be called love by the world predominates over friendship enough to show them as different. Thought and feeling are contrasted in an even stranger way, two opposing sides yet both of one coin and always operating in conjunction even when one is totally predominant and the other seems in total abeyance. Of course, love and friendship are efferent and thought and feeling are afferent.
