The nose. You never get to see your own nose. Even though it is right there, because both the eyes which are constantly used to seeing it, negate each other out. And you never get to see your own nose.
Same applies to the Lover. You lose sight of him. Outside of yourself. Because he is constantly there, in your mind, fiddling with your six senses constantly. And whenever, even if he is outside of you, your eyes, two pairs, four of them, looking into each other, cancel each other out. Like the Lover ceases to exist. Despite being right there, saying, listening, seeing, moving. He effectively becomes a part of you. Begins to live in your consciousness as a thought, an idea, and not as sturdily as the matter, that can be touched, smelled and felt. Though he very can be, pinched, kissed, loved, you forget. Lovers become extensions of each other, or even become one person.
Level of comfort, as it is called, shoots up to an extra-terrestrial high. Suddenly one pair of extra hands seems unnecessary. So does the extra pair of legs. Lovers carry each other, over shoulders, on arms. The other mind of the two feels like an extravagance. They could as well make do with one, you know. Their memoirs merge into a symbiotic haze and they look into the time to come, with one pair of collective eyes, irises.
