None of the girls live at home with their dad. I think they all are out on their own. I wonder how much contact they really have with their dad and how much they truly understand about his current life and what he is looking for or needs in a wife?
I'd say he's a brave man (or maybe stupid) for allowing his daughters to choose a mate for him. Then again, in reality, all they are doing is choosing someone for him to be in contact with for a while...then break-up.
I wonder if Marty is allowed to contact any of the girls who were eliminated after the eventual break-up with the one the girls chose.
