Are menus really necessary?

I found Sheri's confession about not planning menus very interesting. She is sooooo organized that I naturally assumed this carried to all parts of her life. I must confess, I never actually plan menus on paper. I think about what I would like to have, factor in what is on sale and then I too, fly by the seat of my pants. The last few times at the store, Wm. accused me of just cooking the same 5 things every week, just mixing them up. Not true, although it may seem like that. I try to cook things that will allow me to have leftovers for his lunch and leftovers for Uncle Roy. Reading some of the comments on Sheri's blog, I feel a little twinge of guilt for not planning menus. That probably would cut down on all the quick runs to the store for something we have forgotten. I like the prices at WalMart but Wm. does not like their produce or meat. Wegman's have great produce and meat but the prices are higher on a lot of things. Too many choices in both stores and going to WalMart almost always means spending more that you plan (face it, who won't wander into the retail side of the store). Wm. has always said that it all evens out in the end so just shopping Wegman's is smarter. I think that as long as we need vitamins, band aids, etc from the retail side anyway, why not get the groceries that are cheaper at WalMart then. Maybe you just can't teach an old dog new tricks!
On a lighter note, I heard something this morning that I have never heard before. Someone begging to clean the toilet! Matt loves to clean anything, yes, even the toilet. (well what can you expect, his father is Mr. Clean) I finally was worn down enough that I gave in and he was jumping up and down singing "yea, I can clean the toilet". Well, at least someone can sing about it!
