Why?

So its come to this. After years of knowing you, its finally come to this. Im so used to seeing you walk in front of me, so used to seeing you and your shadow getting further away, that now, if you were to walk away, in a big crowd, i would've recognised you instantly. But i bet, if you were to walk towards me right now, i doubt i would know its you. Because all this while, one of the most vivid things that i remember about you, is how you look from the back. Your face seems all hazy now, like a dream. Yes, you are like a dream. And dreams will one day be forgotten. And you will forget me one day too, regardless of how insane i was, regardless of how i tried to stand out amongst everyone.

Isnt it sad? Is it love, infatuation or obsession? I guess i will never know.
