Bob: Can you send me the instructions on how to send a PDF to a kindle?
Dan: Yeah, sure. What book do you want to copy over?
Bob: Origin by Dan Brown. I got a PDF copy of it, but I hate reading books on the computer.
Dan: Cool. Maybe you can send a copy to me later :)
Bob: Sure, no problem. There's a cool website that has all the latest releases.
Dan: What's the site?
Bob: Allbooks4free.com
Dan: Ok, I'll check it out.
