movie: 20th century girl

"remember what you said a while ago? that if you like someone then you can't sleep at night, the food you eat becomes tasteless, and listening to music makes you cry. actually, I sleep fine at night, and my food tastes even better than usual, and I feel like dancing when I listen to music. It's strange, though. when I think of him, my heart hurts a bit. If this is love, then I think I'm in love."
