Who am I?

The moral of this one, you tell me...

I am neither here nor there, there nor here. I am invisible to the naked eye, yet all can see me if they wish it. I am the flower that fades, here today and gone tomorrow. I am a wave on the ocean, just vapor in the air. I am the person who is only seen and only stands out when I am introduced by someone who is noticeable. You know, I know it, we all do self-consciencly in our minds, it is painfully obvious of all the denials of the truth when it is right in front of them how they act. I don't make it sound like I am alone, there are others, I don't know them of course for we have not been introduced by someone of significance. Funny how things come around full circle isn't it? But really who am I? Who I am to talk to you, to look at you, to even be in the same room as you. Who am I you ask, you tell me. Seriously I want to know. Who I am, we have always been obsessed with this question. Yet we almost never find the answer, I know who you are, you are a god. And I am not. So tell me your Hines...Who am I?
