Having a very greedy roommate is a scary thing. My roommate Huahua is a particularly greedy person. Every time I buy something, she pounces on it like a wolf, completely forgetting about politeness.
Afterwards, she ate it with big mouthfuls. Once I deliberately brought a fake bread back, but when she bit it, the bun fell off, and two of her teeth fell out. She cried and flushed her nose in the toilet... and she never looked back again.
Don't dare to steal my things.
