Crystal

This is Crystal, and she is your sibling's best friend! ... Your sibling brings her over to your house almost every day, so you know a lot about Crystal. ... This includes: The fact that she loves reading sci-fi books. Her favorite color: Purple. And her favorite food: Spaghetti. ... One day, your sibling was shopping at a nearby mall, and Crystal came to your house on her own! ... (be literally anything you'd like! ^_^)
