Wow. I feel like Nabokov is validating how I've always read. I always appreciate and enjoy books (and short stories) more upon re-reading. I re-read multiple times, too. What he says rings very true for me.

I always had trouble explaining to my friends why I enjoy, while browsing a bookstore, picking up books I already own, looking for a parapgraph I know I enjoy and reading it. It's a bit like looking for clips of your favorite movies on YouTube.
