haetian
A haetian is someone who doesn't like you and acts like you're the worst person ever. They don't even have a good reason.
My friend is a haetian. She said I was a bad friend just because I didn't text her back.
My uncle is a haetian. He said I was a bad kid just because I spilled soda on his shoes.
My dog is a haetian. He barked at me when I was just trying to eat my sandwich.
