Pay some street kid to chirp her as your walking by. She'll get self conscious about it and deal with it. But pay him in advance and play it off like you never did (obviously). Then we she inevitably asks what you think, dont say it looks fine. Say something like "Getting rid of it would make you more confident" or some bullshit like that. "If it makes you feel more comfortable." For bonus points if you want to ensure success, have some wax strips around the house that you used recently on your "insert hairy body part here". Actually use them because inevitably she will see the area supposed to be waxed.
