I wonder about her female friends too. Girls tend to hang around in groups between 11 and 15/16, and really, one can't live without girlfriends that listen to your complaints about stupid boys and periods.

Even more so, I wonder who is she. She is not even that close to Ron and Harry, as they don't know that much about her. Who does she cry with when she's sad? Ginny? There must be more to her life than the books show, as they have yet to show us she's a complete entity with, like, interests beyond learning, house elves and fighting evil ^^
