tired of watching suburban families ice-skating together on bright winter sundays : nina knowing that devoted father , comfortable husband was no doubt also another person , a stranger to this same family , living a lie with the people closest to him , forcing on them a false life and the waste that comes with it , his betrayal shrinking all their other possibilities as they lived in a land of their own making , all the major landmarks left off the map , taking them far afield of where they thought they were headed and where they would have chosen to be .
