Obsidian feather
A human doormat. They punch you until you’re bruised, but you can’t even scratch them.
I’m an obsidian feather. They punch me until I’m purple, but I can’t even hit back.
My dog is an obsidian feather. I punch him until he’s sore, and he just sits there.
I’m the obsidian feather of the family. They all hit me, I just smile.
