Last spring when Cassie shaved a side of her hair clean, people went crazy. Why, they thought, would a young girl do such a crazy stunt and make her head bald on one side? I personally didn't mind the look. In fact the cut made me notice one of Cassie's greatest assets: her perfectly arched eyebrows.
