Love, Golden Fish and Owl

Once upon a time there lived a young man, named Bid Bardle.
And he fell in love with a girl, living in the same village.

The girl was pretty and with a kind soul but she did not feel the same way towards Bid.
Whenever he tried to confess his love she stopped him.

Bid was going mad with longing; day after day he could not think about anything else but the girl.

On a clear and warm night he was standing outside, looking at the sky and dreaming about the girl.
And suddenly he saw a falling star!
He quickly made a wish – "I want to find a path to the heart of my beloved".

And, lo and behold!
The star flared up and disappeared.
And in its place appeared an owl with a small bowl in its talons.

The owl flew up to the guy.
He snatched the bowl with an impatient movement and in doing so accidentally damaged the owl's wing.

Then he looked inside the bowl and, lo and behold!
There was a Golden Fish inside with bright shining scales.
And the fish spoke to him in a human voice, "Bid Bardle, I am a magical fish. I can grant you three wishes."

"I have only one wish and no other," said Bid,
- I am in love with a girl and I want her to love me back.
- I want her to love me as long as she lives.
- I want all her thoughts and feelings to be about me and only about me.

"Let it be as you wish," said Golden Fish (and its golden scales faded a bit),
- You have two more wishes to be granted.
- So, take me and let me live with you.
- If in the future you want anything else from me – say so.
- Also take with you that owl that you crippled and take care of it; you are now responsible for it.

The very next day Bid proposed to the girl and a few days later they got married.
They lived happily together, both taking care of Golden Fish and an owl.

For a few weeks Bid was on the heights of bliss.
But then his happiness faded a bit.
He still loved his young wife with all his heart, but she now was not the same as before.

She had forgotten her old friends; she also became indifferent to her parents.
If some other woman simply smiled at Bid, his young wife looked away, trying to hide her distress.
And when he was coming back home in the evening he was met with a sigh of relief, like if his mere absence caused her suffering.

She never reproached him with a single word, but he felt that her life had become one big misery.

Finally he could not bear it anymore.

"Golden Fish," said Bid Bardle, "I made a grave mistake. Could you please fix it?"
- Make my wife stop loving me, so that she will be able to get her real life back.
- I know that she will leave me, but I deserve it.

"Let it be as you wish," said Golden Fish (and its golden scales became completely dull),
- You have now one wish left.

As soon as these words were spoken, young Mrs. Bardle fell dead.

Remember, the first wish was "I want her to love me as long as she lives".
Therefore the only way for her to stop loving Bid would be to die.

Bid was devastated.
He felt that he has nothing to live for.
But killing himself did not feel right either; it would be too easy a way out.

An idea formed in his mind and, without thinking about it, he blurted out,
- Golden Fish, here is my last wish:
- Give me the ability to write stories that would help other people avoid making the same mistakes.

Golden Fish said nothing; it turned slowly to Bid and stared at him unblinkingly.

Bid turned away and his gaze fell on the owl with the broken wing.
"Wait!" he cried, "Let me change my last wish."
He took a deep breath and said firmly, "Fix the wing of this bird."

"Let it be as you wish," said Golden Fish (and its scales became golden and bright again).

And, lo and behold!
The owl's broken wing became as good as new.
The owl hooted and stretched its wings, testing if they work properly.

Then it grabbed the bowl with the Golden Fish and flew out of the window.

Bid Bardle never married again.
He went wandering through towns and villages, listening to folk tales.
From time to time he retold these tales to those who did not know them.
Then, without knowing how, he began to change these tales, adding to them pieces of his own.

The time came when he understood (or thought that he understood),
- Yes, the Golden Fish did give me ability to write!
- As was my third wish.
- And my last wish – about owl's broken wing – it was granted because it came from my very heart, from all the good that I have in my soul.

That is how he started to write his famous tales and publish them under the pen name 'Beedle the Bard'.

And until his death he never learned that no magic can give talent; that talent either is there or is not.
(Talent is one of the five Principal Exceptions to Gamp's Law of Elemental Transfiguration)

And fanfiction reviews are another such exception!
So, dear reader, either you write a review by yourself or it won't be here.
