I Was Once a Part of You

I was once a part of you, and of course you know it too ! We shared a body and a heartbeat... I wouldn't mind if it was to repeat... For 9 whole months we were one... But with my birth it all begun ! I began to see that we weren't the same.... But I didn't know, who I was to blame ! Was it the world or was it my genes ? I still don't understand what it really means, to be so different, yet one with you... and I am sure, you don't know too !
