The Good Dishes

We keep the good dishes in a cupboard, only taking them out for special occasions.
On the other hand, we keep the evil dishes in an iron-bound wooden chest in the basement.
They rattle and clatter angrily in their prison, demanding to be set free.
Not a chance. The last time we let them out, they gave the mayor and his wife food poisoning.
We’ve tried to destroy them, but every time we break a plate or a dish, the pieces reassemble themselves the next morning.
It’s best to keep them locked up, no matter how pretty they are.
