I may not have a walk-in closet or granite countertops, but I do have this:

Our massive, sandstone fireplace is in the living room, and backs onto our bedroom wall. A good fire in it on a nippy afternoon keeps our room warm nearly until morning.

Of course, we also have a weird little adjunct fireplace on the back porch and a wood burner in the basement, neither of which we’ve ever even tried to use. What I’m telling you is that, in event of apocalypse, bring over your junk mail, and we’ll all make it through the winter just fine.
