Cover art for Home Is a Fire lyrics by Death Cab for Cutie

I think this song is about a relation ship or a family per say. "Sleep, sleep with the lights on. Shutter and shades drawn." This refers to fear or tension it can bring. "There are too many windows." This refers to that there are too many possible routes the relation ship can go (some bad/good). "Noise, cars on the freeway." Those are the people who don't want to be in a committed relation ship so they leave. Noise means that they are loud which means there are many of them (which is very true). "Home is a fire" I think this refers that home is a great place of light and warmth and it's a place of bad and/or destruction. "Walls built up around us. But the bricks make me nervous. They're only so strong" The walls are the foundation of the home or relationship. The foundation or the bricks are making him nervous because they are only so strong (how many fights or bad happening can this relationship take before it crumbles?) is what I think it means. Maybe this is about Ben's fear of a marriage or home ending with Zoey. I mean it makes sense because Ben has clearly stated that everything ends.
