Patience is a Virtue

A young princess, with dark-red hair and brown eyes, the colour of melting milk-chocolate, and one that was called Seraphine, had everything that she had ever wished for.
For the first fifteen years everything ran smoothly in the kingdom, and in the mind of the little spoilt damsel - for she knew that if only she said "I want,", then surely every time the thing became hers.

One evening, the Angel of Sera visited her. It was her own bodyguard, very modest, very polite, with a plump body clothed in a white dress, satisfying as snow, a halo about its head and curly blonde locks streaming up to its shoulders.
The first time it visited her, it was determined to just let the girl know that her bodyguard in fact wasn't just some make-believe, and in vain tried to convince her that she wasn't going mad or just dreaming.
"Fine! Then right this moment I want you to bring me a bit of stardust, enclosed in a lovely jar of bronze!" Sera said decidedly, a bit of a pucker about her lips, and was surprised when a moment after it had gone, the Angel returned with a jar full of gleaming dust.

Every day after that, Sera called upon her Angel, and every time, she wished for the impossible. "A leprechaun!" and the fat little man in green was delivered to her window. "A dress as silky as water!" and the next evening she went to the ball in just that, charming a young prince who instantly asked to dance eight times in a row. "A bird made out of fire!" and the little creature soon burned down her most treasured toy, leaving the girl fuming, and wickedly wishing for other things also. "I want a siren to sing and lull me to sleep every evening so that I don't have grey bags under my eyes the next morning!" and so, so on it went.

The Angel, meanwhile, was becoming very tired as days passed; its power was drained from it, but it wasn't it its nature to say "No" to a little girl.
One day, however, Sera crossed all limits.
"I want you to bring me the potion of love, made from a pinch of lava, a teaspoon from the moon and a cup full of mermaid tears."

So the Angel flew to the Lands of the Unknown and tried its best. Every day, however, it was called upon, and the same question was asked over and over again: "Are you done, yet?" it was the same every twenty-four hours - for the little princess was not born to wait.

On one of it's attempts, the Angel was doing very rather well - why, it already had a flask full of salty tears, a pinch of lava stowed away safely, and was just finishing collecting the bit of moon - when Sera called it to herself, and the Angel fell right off in its surprise, never to be seen again.
That night, the princess wondered why her Guardian hadn't come - though, she never received an answer.

Since her Angel was gone, many a bad thing happened to her for the rest of her life - because patience is a virtue everyone must have.
