Somebody Tell Me is This is How Normal 13-Year-Olds Flirt These Days

[Update, 12/4/09: In response to a couple of comments below, I have decided to edit this post slightly.]

So Megan, our oldest daughter, thirteen years old, comes up to show me something funny a friend at school made for her. It's a little book. A picture book.

The main character is Megan the Cannibal. She is stalking her friend. His drawings of Megan and himself are crude, but funny and effective, in a cartoonish sort of way.

There is a brief narration which attends each page in the little book. Megan is a vicious cannibal, tracking her prey through the hallways of their school. Her prey flees; she follows. He hides in his bedroom at home, but Megan follows him, breaking into the house through the roof. She confronts him, binds him, blindfolds him, then takes him to her lair.

There, using previously unannounced superpowers, Megan shrinks him with her powerful Shrinking Ray Eyes. He runs for it. He hides somewhere in the kitchen. Eventually, however, Megan the Cannibal finds him and, in one gulp, consumes him.

The final scenes of the book show a satisfied Megan the Cannibal, smacking her lips, while her friend stews (literally, I suppose) with a worried expression on his face, surrounded by Megan's stomach acids. The End.

She finds it silly and hilarious and laughs about it. I find myself perplexed. My wife looks at me curiously, wondering what I'm reading into the story. I'm not sure. Suggestions, anyone? Parents of 13-year-olds, particularly those skilled in literary deconstruction and/or child psychology, are encouraged to reply.
