Kuch to Hua Hai, Kuch Ho Gaya Hai

I am watching the movie 'Kal Ho Na Ho' for probably the Nth time.Yet somehow when the song "Kuch to Hua Hai" came I was smiling the whole time (yet again).Watching Preity Zinta and Saif Ali Khan being so happy makes me feel happy also.Makes falling love sound like some sort of fantasy.Well some may argue its a movie after all, you are supposed to feel that way.I m not sure if I have ever been in love but to me being in love would probably be as described in the song.
