I come from a family of readers. I didn't know anyone else who had a library in their home. No, it wasn't on the Beauty and the Beast level that practically took up a wing of a castle, but it did have a rolling ladder that almost every single person I ever took in there would climb on and try to make it swing like Belle did in the opening montage.
My mother swings between the classics and thought-provoking literature to what she called her "candy books" aka sci-fi and fantasy. On the other hand, my dad is a pure non-fiction kind of guy. Sure, he'll make time for the occasional modern thriller (I'm pretty sure he has a man-crush on Jack Reacher and Jack Ryan), but mostly he reaches for pure fact. I certainly take more after my mom than my dad, but I've learned to enjoy the odd non-fiction.
