Actually I DO know everyone’s sex. It could be unrelated or it might actually be because I’m psychic. I don’t expect my abilities to be understood in the minds of the ungifted like yourself (no offense), because the mystical arts work in mysterious ways. But either way, my gift is a big part of my identity, and identity is sacred so you’ll just have to take my word for it – that I can identify sex with 99.9999% accuracy.
