Bacterium

-Sit down. Took you long enough to find me, I've been wanting to talk to you. I got to say... I have mixed feelings about that.
-S... so is this the part where... Where you kill me?
-You have an inflated sense of your importance. To a thing like me, a thing like you, well... Think how you'd feel if a bacterium sat at your table and started to get snarky. This is one little planet in one tiny solar system in a galaxy that's barely out of its diapers. I'm old, Dean. Very old. So I invite you to contemplate how insignificant I find you.
