One book that changed your life. I dunno man, this is a little melodramatic for my tastes. No answer.
One book you've read more than once. Arthur Clarke's The Songs of Distant Earth.
One book you'd want on a desert island. The Boy Scouts' Handbook. No question about that one.
One book that made you laugh. Anything by Christopher Moore or Terry Pratchett.
One book that made you cry. I leak a little when reading a good story entirely too easily - oddly enough, usually in books that aren't supposed to be soppy or emotional. I'm more likely to feel a sudden upwelling of tears at a random moment of one friend coming to another's aid in a comedy or an adventure than anything else. Actual "tear-jerker" type things tend to leave me high, dry, and mildly disgusted.
One book that you wish you had written. Why would I want to write somebody else's book? I've often wished I had the focus to write a book of my own, though. But it's not too likely to happen - for the same reasons I have very few pictures of myself and the things I've done. I feel like you make a conscious decision to stop living your life and start documenting it instead, when you do that. So I generally don't.
One book you wish had never been written. I'm not big on censorship. It would be easy to say something like how much better a place the world would be if the torah, the koran, and the christian bible had all three never been written... but that would be facile and wrong, because other things would simply have taken the places they fill, with the same results. On the other hand, my hatred for Charles Dickens' writing is LEGENDARY, and I can't fucking believe nobody's figured out yet that he'd never even have gotten a publisher if he'd been born a hundred years later. Not because we're all shallow and [whatever] in these degraded latter days, but because the man fucking SUCKED and needed a truly vicious and invasive editor to strip away four out of every five words he ever wrote.
One book you're currently reading. Meh. A James Hogan sci-fi book. It's nothing special.
One book you've been meaning to read. Gibbons' Decline and Fall of the Roman Empire. I'm intensely interested in the time period, and adore the idea of getting bits and pieces of actual writings from contemporaries of that era, however filtered-down by translation. Unfortunately, it's dry. Hideously so. I've gotten a few hundred pages into it in bits and chunks at various times, but it is just not an easy read - and what makes it rather worse is that the original Romans whose chunks of text are in it were no great literary minds, either.
