David Foster Wallace left us this past weekend, and the world is a much sadder place for it. I'd first heard his name when in high school, when my most beloved teacher, Ms. Wilson, recommended his magnum opus "Infinite Jest" to me. She knew that I might find the 1,100 page novel a bit daunting, and suggested--if I didn't have the nerve--that I might as well just pick up "Girl With Curious Hair."
