There is much better story telling in "how to survive" for those 7 months though. Forage, Scrounge for food, water. Fuel, wood, keep safe from other survivors... I doubt electricity would still work after 7 months, unless the house got its own solar cells or something. Doubt stock of food and water would hold for 7 months either unless they some serious doomsday preppers to start with, which a "yoga" mom, doesn't really reflect
Can spend a week with the inlaws and be ready to snap, but not because I want to violate them though
