Hi there-

I am curious (i don't have the books with me) if we have ever seen 
Snape in the daylight? He always had the curtains closed in the 
poitions room and then did the same when he moved to the dada room.
it seems to me that he is always in the dark. what is that about?? could he have some vampire tendencies? I realize this is a stretch. just curious. I am also wondering if we know what Snape's patronus is and what his boggart turns into? These were hits given on a website.
