I've been limping along because my knee has been hurting a lot lately. At work, one of my girls (Paige age 3 1/2) asks me what is wrong. I tell her my leg hurts when I walk on it. And she says, "Why don't you say Ow?" I would be saying "Ow" a lot if I said it every time I hurt! Makes me wish I was a little bit younger and less in pain!
