Sister in a Glass House

Tiffany Sedaris yanks a saucepan out of her freezer and plops it on the floor. Eight ice cubes slosh in a couple quarts of water. She wraps her right hand in a paper towel, reaches into her oven and slowly pulls out a slab of glass. It’s asymmetrical, 8 inches wide at its widest, 2 inches thick, and a foot long, and it’s been baking at about 250 degrees for five minutes. Tiffany slips the glass into the saucepan.
