Telling me how you fear that you might die before George RR Martin finishes his next book is of no interest to me whatsoever. There isn't anything I can do about it, and since I haven't read any of them, I don't know what you're talking about when you start making long and involved references to characters in the book.
Trying to debate the organization of the store on etymological terms will only irritate me. Trying to describe your own plan for how books should be shelved, which distinctions of genre and subject you would make, is something that you should take up with someone else. No, we don't have a biography section.
Also, lamenting the fact that we don't carry obscure mathematical and philosophical texts is mostly tiresome. Once again, I usually don't know what you're talking about. I am, indeed, ignorant. Please inquire at the nearest university.
