How could someone even survive with a "bookshelf" that small? I've have way more than a dozen times that, in the room I'm currently in alone. I ran out of shelf space years ago (yes, I've acquired more shelves since then. instantly filled.).
I think you already know that this dude does not read. He probably didn't even read these books. The books are in plain view, on a shelf, and organized for a reason. They're probably the only decorations in the room. I'm willing to bet that he specifically brought them up because he thinks they make him seem smart as opposed to everyone else perceives him; as a clown.
Read tons of those too. The second part is more what I'm referring too, reading is such a big part of my life that I, rather hyperbolic like, said I don't understand how someone could live without. In the literal sense I do understand, because that's most people.
I regularly max holds and checkouts. Libraries are super cool, I especially love how they usually have documents that are hard to find other places. Obscure technical books, local budget info, and the like.
