Just remind her
about women and the Infinite Wardrobe Theorem:
Give a woman a wardrobe and she'll fill it with clothes, handbags and shoes
Give a woman another wardrobe and she'll fill it with clothes, handbags and shoes
...another wardrobe (to the power n) and she'll fill it with clothes, handbags and shoes.
(where n is a positive integer and does not equal 0)
