Yes, that's right! So, the little princess chased after her brothers for hours and hours, never slowing down or stopping, following after them into the woods for as long as she could still see them, and after they outflew her she simply kept running in the same direction as she'd last seen them go. She ran and ran, and after a whole day and night of running, she was dreadfully tired and thought she couldn't bear to run a single step farther.

But luckily, just about that time, she happened to come across a little hut that looked like a hunter's den, and there didn't seem to be anyone around inside. And she was so awfully tired of running that she thought it simply couldn't hurt to lie down inside and sleep a bit, and make her apologies to whoever owned it once she saw them, and be on her way as fast as she could. So she went inside and curled up on the floor beneath a table so as to be as small and unobtrusive as possible, and fell fast asleep.

But then, a bit later, the strangest sound roused her from sleep--the sound of feathers rustling! And she opened her eyes just in time to see six swans fly in the open window and land in the middle of the floor, and shake off their wings and feathers to transform into her brothers again!

And oh, she was so wonderfully happy to see all of them, but they weren't quite so happy to see her. "Oh, little sister," they said sadly, "This is no hunter's hut! This is a robber's den, and if you stay here you'll be in terrible danger, for they will come back and catch you."

And then they explained that the enchantment on them was such that every night, for just a quarter of an hour, they could shed off their feathered swan skins and become human princes again, but then once that time was up, they would be turned back into swans and left to soar about that way for the entire rest of the day.
