Nothing particularly weird about having it on the shelf admittedly, I'm really just referencing those things one encounters while visiting someone's home that serve as 'Uh... okay...' moments of insight. I should imagine both of our bookshelves just scream bookworm regardless of individual items but people's households are usually indicative and if your buddy's got a Nazi flag hanging up and he says 'Yeah, Grandpa brought that over in 1945' and you ask 'army?' and he says 'Nah, Luftwaffe' a feeling of creepiness is permissible subject to later discreet verification. I'm just talking about those general moments in life where someone makes a comment or slip that makes one pause for serious character reappraisal, not many specific items or comments without context are really auto-creeps.
