It has always been my experience that when the wife stops working around the house, a repair is not possible.
Therefore, you have a couple of options:
Replace--this leads to all kinds of issues, especially once you have had your spouse broken in properly..it may take weeks before the new spouse will be trained to bring you your slippers and beer while you are watching TV. Keep in mind that there is not much market for used Wives out there, so if you decide to go this route, you will definitely take a beating on the trade in. Also be aware that new units may be subject to a manufacturing flaw called PMS...not sure exactly what that is, but I am under the impression that it involves the unit throwing cutlery, plates, glassware and cookware at inopportune times. Therefore all new units come with an Underwriters Labs label warning of this fact and a legal disclaimer that states that many men have been injured in the past due to this manufacturing defect.
Do Without--This is what they made disposeable paper plates and cutlery. A viable option, however it is difficult to cut a 2" Steak with a plastic knife (however, I tend towards using my Rambo survival knife for that purpose--just wipe it off when you are done and it will be great).
