Imminent attack

There's an army advancing on my house in Duluth. I see them from the window in my parents' room and rush to hide. My first thought is to try the closets, but I later decide that they're too obvious a choice and decide to go to the attic, which is accessed from a door in my little brother's room, instead. I'm shocked by how large it is; it's much larger than I remember it being. I set to work slicing an old mattress in half and carving out a body-shaped hole in the foam, as well as some breathing  holes. I've just climbed in when I realize that the soldiers will probably slash through the mattress with their machetes, since they always do that.
