Here are a few of the "reasons" I've been given -- none of which have been persuasive, by the way. The most anyone who asks for a free book is likely to get is . . . quoted in this blog!
* I'm your biggest fan and I know where you live.
* I'm on disability.
* Cheese attacks me.
* Ah kin reevoo it fer ya 'n' tell mah frinds t'buy it nex' time they pawn sumpin.
* I am [Welsh] [a mariachi fan] [a Fourth Degree Alex Gardner initiate] [psychic] [a writer] [a spy] so it's only right.
* The warden won't let me buy anything.
(I do occasionally donate a book to a charity auction, and once in a while I give one as a gift, although that always seems a bit presumptuous to me. But the truth is, I can't afford to give my books away. I need to sell 'em just to pay for buyin' them to sell!)
