Sara and I got into Harry Potter around the same time. I remember as Harry Potter newbies during Winter Break of 02/03, we sat in Applebees discussing the "look of triumph" in Dumbledore's eyes and what that could possibly mean. For hours. When I went back to Gainesville, we'd be rereading the books and calling each other at all sorts of odd times, steeping out of the shower to write something down before we forgot it, and generally thinking up theories constantly.
Last night I read something in Deathly Hallows I hadn't seen before. Snape is a bat?
I am so going back to my years-old vampire theory.
