Take him in?
He's a grown man with a son. Sarah doesn't have to take him in. Just be cordial with the repentant father of her grandson.
She doesn’t need to be cordial. He is trash and has trashed Bristol in a very public way.
He is just trying to get back in the fold to snoop for the left to give them personal info before the 2012 elections.
Shutting up and not bothering them anymore accept to pay for and visit his kid would be a real way of apologizing.
