Tell her men need their space and their own alone time. Sometimes its just for the most inane and stupid reasons, like farting, others are to contemplate imminent death after the UN kicks your door while you scream behind a knocked table with your shotgun: "I HATE THE ANTICHRIST" Seriously. Open your mind to your deepest thoughts to her. She wont understand, and that fact alone is reason enough for her to leave you alone for a moment or so.
