Wait until she has a kid. When my wife was pregnant, she gained a lot of weight during her pregnancy. Her doctor told her that her excessive weight gain could endanger the baby and she should exercise and eat healthy. Nope. Not gonna happen. Laying up on the couch inhaling cookies and such. I was at the end of my rope. We were arguing about it, and she said, "I'm eating for two now!" I responded, "Yea, but one of you only weighs two pounds." She's my ex-wife now . . .
