The word Impostor keeps coming up every time a trans woman writes about herself. It is there, just below the surface, despite all the estrogen and progesterone, under all the skin-colour foundation and pink lipstick and shiny earrings. It is behind the pads on our breast, cushioning the tender nipples. The feeling, and the word - impostor. We are impostors when we try to be us, and when we try to be what you think we are.
