Being at home tired Fridays to Sunday afternoons is not what I would call good parenting. It means the wife (and I guess we're mostly talking about women here) is carrying the family.
Spot on - the wife/partner carrying the family is the biggest issue in my daily 4hr commute. Also an issue is just not able to be there in an emergency. For example, my wife locked herself out of the house yesterday and fortunately her parents who are close have a spare key. But children or pets get sick/injured and you really need to be close and that is always a worry.
