That may be true, but real life isn't always so easy. My husband was unemployed for a time, and he stayed home with the children. He wasn't very comfortable with it, and it wasn't something he really CHOSE to do, but lemme tell ya, there were lots of guys I met that sort of envied him the time he got to spend with our boys. He's not a good housekeeper, lol, so I continued doing that, but he did a great job with the boys, whether or not he was "biblically and genetically predisposed" to be the head of our house. In fact, I would say that his status in that regard was largely unchanged...it takes more to being a husband and father than just bringing home the bacon, imo.
After 13 years, my housekeeping skills still suck. I am however a great father if I do toot my own home. I'm not a bad educator either as it turns out.
