Just tap your chin, give her a nice smile and politely remind her to keep her guard up.

You don't have to be restricted to fighting in close, find your best range which let's you land more your punches. Shortening up the punches and closing the distance can help you as well. Keep her in check, you can use side-stepping to gain the upperhand when she rushes towards you, and your hands when she's leaving herself wide open.

Anyways what this boild down to is a two-sided learning experience for you and her. On her end it's about learning first hand about what a boxer should do, on your side it's about learning control. Good luck.
