I was wondering what people thought about how long it took them to forget a good book. Or, to put it another way, when is it time to re-read a (genre or non-genre) classic? I know it varies - some books fade fast and some stick forever for whatever strange reason, but generally speaking. I was wondering because of Connavar's thread on Herman Hesse. In order, I've read Steppenwolf, Demian, Siddartha, and Narcissus and Goldmund and I liked them in that order but I couldn't think of a thing to say about them except that I liked the first one or two and still respected the last couple-three. I still have Stories of Five Decades and Magister Ludi (aka The Glass Bead Game) waiting to be read after years and years. It's just odd to have six books of an author on the shelves, to have read four of them, and to have nothing to contribute to a thread about him.
