Trixie was walking through the park with her nose in the air when she tripped over something and fell flat on her face. Furious, she picked herself up to confront the offending object, but stopped short when she saw what it was. It was a sack with a note attached to the side of it. It read:
Dear stranger,
Congratulations on discovering my life savings. After I obtained all of this money, I realized that I wanted to spend the rest of my life exploring Tartarus and that I wouldn't need all this money. I left it out for anypony to find, for I believe in making others happy. I would've donated it to charity, but I have absolutely no idea how to do that. Enjoy your money. The bag has about five million bits in it.
Trixie flung the bag over her back and did a little excited dance before galloping full speed to the store. In the hours that followed, she bought a hot tub, a golden statue of herself, a giant diamond, an assortment of fancy overpriced pastries, lots of other unnecessary things and a mansion to house it all in.
Later that night when she was relaxing in her hot tub with her personal assistant feeding her fancy chocolates, she realized that with all the stuff she had she wouldn't be able to exit her bathroom. Panicked, she sent a letter to Twilight Sparkle, who would surely know how to fix this. Twilight Sparkle replied back, suggesting that maybe she should donate all of her stuff to more unfortunate ponies.
Help others? No way! Trixie fired up her horn and blew up her entire mansion. Unfortunately, her old house was located next to her mansion, so that blew up too.
A couple days later she tried to go to a homeless shelter, but they kicked her out because of the way she had so callously wasted her money. Trixie was forced to get a job as a sewage cleaner for the next week until she could save up to pay the rent for her trailer.
