A guy sent a message via SMS to a girl that he had feelings for with a context like this: "Hi! When you see this message, you owe me a date. Delete this the text, you owe me a girlfriend. Save this text, you owe me a kiss. Reply to me, you owe me everything. And if there's no response from you, that means...you have fell in love with me!" A moment later, that boy received a message from a stranger: "I'm her boyfriend. See this message, meet me tonight. Delete this text, I 'owe' you 100 punches. Save this text, I continue 'owing' you 200 kicks in your butt. Reply to me, you'll 'deserve' even more. No response? Coming to your house tonight is my only choice!"
