This scene is from the movie Cruel Intensions, adn it's the only scene I ever really cried and laughed at the same time.. I wouldnt want to spoil it for the people who still want to see the movie (this scene is the ending, so it's not really fun to see the ending before you saw the movie), so you can pick your experience :D.
Experience #1: You've never seen the movie, but you want to.
Please listen to this song
It's used in the end-scene, but it's an amazing song on it's own!
Experience #2: Option 1: You've never seen the movie, and your not planning to.
Option 2: You saw the movie, an you would like to see the genius end-scene again.
For the option 1-people: I'll give a short explanation. The dark-haired girl is called Kathryn. A populair "perfect"girl, who everyone looks up to, and the step-sister of Sebastian, the dead boy who's on the picture in the beginning. In the movie, K& S had a bet. If Sebastian could pull it of to get the blond girl (who's in the little-girls-room with Kathryn) Annet in bed with him, He wins. If he cant, then Kathryn wins. This bet totaly gets out of hand, patly because Annet and Sebastian fall in love, and Kathryn becomes jeleous. In the end Sebastian dies, because of a lie Katrhyn told. She thinks she can get away with it, but she didn't expect Sebastian's Journal to show up.
