Princess Zaria and the college tears

Princess Zaria has an older brother who left for college last week. It should be a happy occassion as this is a major milestone but not in Princess Zaria's eyes. She cried for an hour after his departure. Let me give some background info: Zaria and her brother are 11 years apart. I didn't think they would have anything in common but seven years later, they are as thick as thieves. They watch cartoons together, they have the same favorite food--pizza, they play board games together ; they have been virtually unseparable until now. Please leave your comments as to how Princess Zaria should deal with this transition.
