Look At You and Smile

I smile when i look at you And hope you smile back When i see you finally do I wake up and find the real facts You dont feel the same i do about you And i dont think you will at all But i relize this and back away But i won't come back for a very long time So you won't see me at all Until you notice that im gone Then it will all be switched around You will like me like i did with you And you'll find out what i found You'll go through the same pain you put me through Til it all comes to a end Me and you will turn out together forever But i wonder why it took so long to evolve
