Suddenly, Derek thought of dozens of things to wish for. And his first wish would be for friendship. Yes, he wanted to be alone, and he always was alone. But he always wondered what it would be like to have a friend, someone that he could share his misery with. He had "friends" on the internet, in chatrooms. But he wanted someone he could see, and touch.
But he didn't simply want to invent a friend. He wanted someone that already existed. But, of course, as far as Derek knew he was the only emo in town. He'd have to make someone an emo, and since he had the power of the wishing stone in his possession, it was very possible to do.
Derek decided to use his only "real" friend (his razor blade) to make it all possible. He took it out of his pocket, and looked at it. "You're getting promoted, my friend." He squeezed the stone in his other hand and said "I wish that when I cut a person with this razor blade, he or she becomes an emo and my friend." The stone glowed and then his razor changed color, from metal gray to black.
"Now, who should I use it on first?"
