Sometimes callers from a distance invade my solitude, and it is on these occasions that I realize how absolutely alone each individual is, and how far away from his neighbour; and while they talk (generally about babies, past, present, and to come), I fall to wondering at the vast and impassable distance that separates one's own soul from the soul of the person sitting in the next chair.
