opia - n. the ambiguous intensity of looking someone in the eye, which can feel simultaneously invasive and vulnerable--their pupils glittering, bottomless and opaque--as if you were peering through a hole in the door of a house, able to tell that there's someone standing there, but unable to tell if you're looking in or looking out. - Dictionary of Obscure Sorrows 11.1.18 - 12.31.18
