Relationship advice...from 4000+ years ago

To continue Black History Year, here's some relationship advice from over 4000 years ago.  The wisdom of Africa is much older than we are lead to believe.  From the Teachings of Ptahhotep:

21. When you prosper and establish your home, love your wife with ardor.  Then fill her belly and clothe her back.  Caress her.  Fulfill her wished for as long as you live.  She is a fertile field for her husband.  Do not be brutal.  Good manners will influence her better than force.  Do not contend with her in the courts.  Keep her from the need to resort to outside powers.  Her eye is her storm when she gazes.  It is by such treatment that she will be compelled to stay in your house.
