Maybe I am reading too much into this, but after watching the video again, I dunno what it was about her, but something makes me wonder if she was acting all along. Maybe she just has awkward behavior, but something just seems like at times she is putting on a show, and not legitimately as upset as she'd like to appear. I could be way off base with this theory, and she could be nothing more than a spoiled brat. But at times I wonder if she was doing some sort of (sick) prank, or a project of sorts for sociology, or just trying to "impress" her friends. Not saying it makes her actions right either way.
