We read Name of the Rose in my 10th grade English class and it was a tome that challenged us all for the couple of weeks that we pored over it. I love that book. I've read it one other time since then and it's amazing the number of layers that continue to appear when you read it a second (and, presumably, a third) time. When you spend so much time dissecting somebody's work, you develop a sort of relationship with them, one that forms easily when you have a teacher that distills a deep appreciation for the work you're knee deep in trying to understand.
Mr. Eco you will be missed.
