I guess discretion involves telling a bald-faced lie to a direct yes-or-no question? I figure if you don't want to hear the answer, don't ask the question.
That said, maybe she'd like a little playfulness. Maybe an obviously exaggerated "Not me! I'd never do that sort of thing!"
a fine and enviable madness, this delusion that all questions have answers, and nothing is beyond the reach of a strong left arm.
