If we reason, we would be understood; if we imagine, we would that the airy children of our brain were born anew within another's; if we feel, we would that another's nerves should vibrate to our own, that the beams of their eyes should kindle at once and mix and melt into our own, that lips of motionless ice should not reply to lips quivering and burning with the heart's best blood. This is Love.
Percy Bysshe ShelleyWe look before and after, And pine for what is not; Our sincerest laughter With some pain is fraught; Our sweetest songs are those that tell of saddest thought.
Percy Bysshe Shelley
