Code of the Good Housewife
From Tardis Wiki, the free Doctor Who reference
The Code of the Good Housewife was a written document which Aztec women were required to learn before entering into marriage. Susan was forced to memorise it, and then was quizzed on its contents by Autloc, who found her recitation acceptable.
According to both Susan and Autloc, it was a very brief text.
Tend well your nurseries and your flower beds. Keep clean your pot and stew pan. Do not spend recklessly. Do not destroy or cheapen yourself. You will never have a house or home of your own if you live like that.
