Barbara,
SWMBO says she knows about "tatting lace" but she doesn't know how to do it. Sort of like crocheting, so says she that knows all, sees all. (Let me try: I think it is where you have a bunch of lace and you make little circular stitches around the threads between the holes, so the lace is then attached to a dress or something else you want lace on.) She also knows where the knives go, the spoons and the forks too. I think they have something to do with a drawer somewhere in the kitchen, but I am not sure.
The most important thing a woman should know is how to gain the undying confidence of her husband because she is able to handle whatever comes her way, and bearing up under the long suffering knowledge that her man is incapable of ever finding anything, especially in the refrigerator.
