Pretend I'm Not Here (2000)

Suffering because of the death of his father and the emotional distance of his mother, high-school student Eric kills time by obsessively spying on his neighbors. Compulsively taking notes on everything within binocular range from his bedroom window, he harasses his neighbors by sending unsigned notes and making their private affairs public. The tables turn when one of his prey, a young couple, Tom and Fabienne, figure out the identity of their anonymous tormentor. Meanwhile, Eric is slowly driving his mother and stepfather crazy with his weird, insular activity, and he can't stand his sister Carol's newfound happiness with her beau Simon. IMDB

Magic Triangle
I like delicate European movies as this one. From the beginning, the polts caught my eyes, and the atmosphere was so calm just like I am walking in a central park alone. It is not hard for anyone to find Eric's eccentricity comes from his poor childhood which lacks of love from family members. His father died early, his elder sister left home, his mother was always in anxiety.
Eric are bisexual as I see, at least, he does not refuse homo-sex. At the end, you will find this magic triangle: Eric likes the girl and the boy, the boy likes Eric and the girl, and the girl( although she is tied of homo) likes these two men too. What will happen when three burning hearts come together? Check it out. It will refresh your mind!
