Why ???

do songs, movies, poetry, novels, and generally anything you enjoy, always make you think that your missing something if you don't have it. this almost makes you look for this thing in anyone you see or know. Or even in famous people. If you have this thing you probably won't know what the hell I'm talking about...
even though this thing has never been materialised or even proved to be real and has been made reference to practically since the dawn of writing.
