    Hi All!
Its the day after Christmas. I hope that everyone ate lots of food and got lots of cool gifts. Well enough random thoughts. To the questions I posed in the subject line. 
1 How does chocolate help with Dementors? I know in PoA it tells it warms people up. but unless they melted it how would that work? Can anyone answer this?
2. I've listened to all the hp books from start to finish and i'm
wondering about something. The narrator is Jim Dale. He made Bellatrix
sound either French or German. Is she from any of those countries? or is that just Dales' one of many comedian voices? Hope to get some answers and maybe start some more debates cause its fun.
