check out what she's drawing

You walk over to the girl, knowing that she's a ghost like yourself because of the cold auora around her.
"Hey." you say. she turns around, startled, and backs up against the window, covering whatever she was drawing in the dust. For a few moments, you just stare at each other. She has on a thick velvet-looking coat on, but you can tell that she has a moderately good figure and a small bust. She brushes her light brown hair back, and looks up into your eyes. "hi." she replies, still trying to cover up her drawing. "Whats behind your back?" you ask her, still curious about what she was doing. "Uhh, nothing. nothing at all. Hey, why don't we go somewhere?"
You find this kind of strange that a ghost would have a need for people not to know what she was drawing, but then you remember that most ghosts are strange young people who died violent deaths.
