LOL. Was thinking it's too easy to read something sinister into EVERYTHING EB. I agree it's either Halloween decor or something she picked to illustrate how 'dark' she was.
My husband has a collection of Reaper figurines, there's a very non-sinister back story too long and way O/T to go into here, briefly, we just "Don't Fear the Reaper", they are on display all year round in a cabinet. Other than that, I assure everyone, we're fairly conservative in our home decor tastes.
As for the rest, well all the black paint is a bit OTT but I suppose she thought it looked 'Gothic'. I'd love to think the pretty pink bedroom was done in good faith for Zahra's benefit but somehow I'm not feeling it and am inclined to think along with others that it was 'staged' after the fact. The clothes in the closet gave me pause, it's a pretty scanty wardrobe by normal standards for most girls around that age I know. Ack, maybe I'm guilty of being too suspicious, but I just wonder if it wasn't actually even scantier before the staging (if staging it was) and a trip to a local Goodwill filled it out a bit afterwards, maybe that would explain why AB didn't take those things - they were never actually Zahra's?
