Excerpt from a one-shot I'll be releasing tomorrow

I started writing this a few months back and kind of forgot about it, but seeing as tomorrow is probably the best day to release it, here's an excerpt from a little Hearts and Hooves Day story I'll soon be publishing:

The letter was a bright shade of pink and had the name 'Fluttershy' written exquisitely upon it, though the sender's name had been omitted. It had even been sealed with a heart-shaped piece of wax, and somehow felt extra soft in her hooves as she admired the craftsmanship for such a simple thing. Nevertheless, she admired it more for just a few moments before dropping it off into the mailbox, knowing fully well that there were hundreds more waiting to be delivered. A postmare's job was truly never done.

In her backyard garden, Fluttershy noticed her taking off into the sky. A small surge of anxiety overcame her at the prospect of receiving a letter from an unknown source and an unknown reason. Did she owe somepony money? Was she being delivered bad news of some sort? The possibilities buzzed around in her mind as she put down her trowel and walked around her cottage to retrieve it.

She opened the mailbox, surprised to see the extravagantly-decorated letter addressed to her name. She pulled it out of the box and held it in her hoof, eyeing the heart-shaped seal in the center. Upon realizing the date, yet another surge of anxiety overcame her. To any other pony, of course, this would have been a welcome surprise. But to Fluttershy, it only brought worrisome questions. That was, until she read it.
