What am I?

Or rather what defines me.

What do I really think I am. I don't think I have that clear. Depends on mood, who I talk with, where I am. There are people that claim things about masks. But I'm not so sure a mask isn't part of you. If you can show some sort of facade to the world, what makes you think it's a facade and not part of being you.
Certainties of my life. I was born. I am not a robot. I bleed. Let's not get into the possibility of bleeding robots. I look like the others that call themselves human. Hence the probability of me being human is high. There is however no proof I was born. No gory vids or pics about that. If I am human there are some certainties that go along with that. You are born, at one point you die. Hum, that is about it really. Reflexes? Things that work without me doing anything for that like pumping heart, hum.
