Explicación paso a paso:
One night, there was the most terrible storm. It thundered, it lightninged and the rain poured down in sheets. The king and queen and prince sat round the fire toasting crumpets.
Suddenly there was a ringing of the bell at the palace gates. Putting on his mackintosh, the king went to see who could be outside on such a dreadful night.
When he opened the gates a princess was standing there. But what a sight she was! Water streamed off the ends of her long hair, ran down her clothes and into her shoes.
-"You´d better come in," said the king, leading the princess into the palace where she stood, dripping, and not looking at all like a princess.
- "Yes, I am a princess," she assured them.
The old queen was doubtful. "We´ll soon see about that," she said to herself. And she went to prepare the spare bed for their young visitor.
First she took off all the bedding and then she laid a pea at the very bottom. On top of the pea she put twenty mattresses and on top of the mattresses she put twenty feather beds.
