I am
an Asteroid.
I am a drifter. I go where life leads, which makes me usually a very calm and content sort of person. That or thoroughly apathetic. Usually I keep on doing whatever I'm doing, and it takes something special to make me change my mind.
(If you were not an Asteroid you would be
a Pacman Ghost.)
So I'm like a huge lump of stone that drifts through space??! That ROCKS!
