How come you're still not in a relationship? I asked my sister with a gossipy face.

My sister calmly replied, "Nobody likes me."
So I decided to test her: "If someone liked you, what would you be willing to do for them?"
Sister: "Anything."
Well then, I like you—you're washing the dishes today.
My sister realized she'd been tricked, and instantly jumped up and disappeared from the house.
Alright princes and princesses, you've been tricked too, now it's time to learn some vocabulary.

You're washing the dishes.
The moment you hear "you're washing the dishes," you disappear.
Vanish—to disappear.
