Couldn't imagine that, married to a 13 year old child. Who would want to be married to a girl who only wants to go to the skating rink and hang out at McDonald's while on instagram. How is she going to cook, or clean the house, or get groceries, or pay the bills?
She's my wife but she's not old enough to drive? I would have to drop my 'wife' off to grade school every day. I'd have to make sure she takes a shower, and brushes her teeth, and that she goes to bed at bedtime. That would be super weird.
If I myself was 15 years old, at least it would make more sense. I would be able to relate. We could drive to school together. But as a Daddy, no way in the world I would be able to tolerate that.
