1: Romance novels. Not the dirty kind like a certain skull she knows, the really sappy kind where someone dies at the end.
2: Strawberries. Her favourite fruit. With cream and sugar, or chocolate coated. Doesn't matter which, she loves em all the same.
3: Going commando. She finds it liberating, both physically and mentaly. (FYI, I have no idea where that came from, it's one of thoses things that my pup sprung on me without warning.)
4: Bubble baths. One of the few places in Hogwarts where you can really be alone, is the prefects bathroom (or at least think you are) so sneaking of to the bathroom for a few hours to do absolutely nothing , except maybe read a book or a magazine while relaxing in the water was like a little piece of heaven after the bustle of the common room. She might not be at school anymore but she stilll likes to relax that way.
5: I have no 5. Make one up.
