I read reeeeeeeeally fast, & if I like something I have to own it & I pretty much always re-read it. My main problem in life is remembering to stop reading & do all those other important things that are waiting to be done. Sometimes I re-read a book I loved after a gap of a few years & still love it but it means something different to me because I've changed...I did that with Heinlein's Stranger in a Strange Land - I'd always read my parents' copy so when I left home I didn't read it for several years, then bought it last year & suddenly understood it on a completely different level!
