Hello

Hello, it's nice to meet you.

I would go on, but the person you just met is long gone, after thinking the thought of introduction.
You see, the person you think you know in front of you has theoretically died a long time ago.
Right within this moment, I am someone different; someone new. 
And I keep on changing.
Every day.
Every minute.
Every moment. 

If I were to try and introduce myself, I would never get past the Hi
Since the person I was has long passed away.
I've tried finding ways to stop or
reverse the clock,
so I can finish one simple sentence truthfully. 

I feel like I always have to work with lies,
since the person whom I'm introducing
you to disappeared a long time ago.
Perhaps parts of the people
who I was make a 
part of the current me, 
but they are not all of the short lived me.

I die faster than a neuron fires in the brain.
I change with each cell.
I mutate from what I was each millisecond.

For that matter, who are you?
Try and remember when you started reading this.
How many seconds ago was that?
Are you still who you were then?

For that matter, chances are we'll
only know each other for a moment,
then spend the rest of the time as strangers.
