Visit me at 1899 Labs, http://1889.ca/2012/12/a-fairy-godmother-in-the-modern-world/ , and learn about how wishing works in the modern world. An excerpt:
Magic in fairy tales is not as powerful as you might think. It’s good for the once in a lifetime chance for a change, but the person involved must be ready and able to take on the challenge. It’s rare that someone wishes for something practical. In fact, almost all wish stories are about how wishing is dangerous, and while the wish may be granted, it will almost certainly be harmful. Those kinds of stories are about keeping people in their place.
What kinds of chances do modern people need? An opening where a circumstance makes things different just for a little while.
