talk about Marquis De Sade, killing people, eating rotten genitalia, doing the strangest kind of drugs, living in the slums, going to raves, working out 10 hours a day for a week straight and then do nothing for a week, your all-or-nothing perispective on most questions, making fun of people and thinking you're way above all of them. None of this will be reiceved with a cold stare which trasudates "you're a crazy psychopath".
I wouldn't stare coldly but I wouldn't have a brilliant smile on my face either. It'd be like...'wonder' and 'eeeeeeeeeeew'. I'd think you're crazy though and not hump you back.
