And I'm sure there are Ms. Know-it-alls, too.
I wonder how I ever lived my life before I had DH to tell me how to do everything:
How to load the dishwasher and clothes washer (stuff in as much as you can and expect it to get clean)
How to brush my teeth (you don't really need to use toothpaste, it's wasteful!)
How to raise my daughter (from a previous marriage. She's 23, finishing college, engaged to young doctor and working full time. His two kids have 5 divorces among them and a few drug busts. His daughter has had her kids removed from her care by the state.)
How to weed my garden, how to feed the pets, how to drive the car, etc. etc. Can you believe I ever lived to adulthood without his endless tutoring? What is it with some men, they have to know everything about everything, even when they clearly don't know sunshine from Shinola!
