One cold winter night, sixteen year old Ashley Sanders was home alone, as her parents had gone out to a dinner party at a friend's house. It had been snowing all afternoon, but had just recently stopped. After studying for a while, she decided to relax a little- after all, she finally had the house to herself. She made some popcorn, got a nice warm, fuzzy blanket, and snuggled under it to watch one of her favorite movies.
