Marriage requirements

Noah and I were looking over the grocery ads, and I was quizzing him about good prices.  I asked him if he thought he would do the grocery shopping when he got married or if he would expect his wife to do it.  He said, "I wouldn't mind doing it, but I might not be any good at it.  What if I thought $2.99/lb was a good price for grapes?"  I told him that's why I'm teaching him what good prices are.  He said, "It's a lot to remember.  I probably won't be good at it."  I said, "What if your wife isn't good at it either?"  He gave me a look and said, "Why would I marry her if she doesn't know how to buy groceries?"
