They're not human. They want to die but only kinda. They come to Earth at night to drink Earth liquor and smoke Earth weed and watch Earth television. They have a mixtape for the ship, but their dubbing equipment doesn't work right. They'll never be as cool as the Earth kids.
“This was the way the night had cashed in. Choices had been made and things happened, and here we were. It was sad, and funny. My life was made of this. Stuff like this.”
