So! Here you have a result of boredom.

Paige had a hard time growing up.
The poor part of Trottingham, abusive parents, bullies and bad teachers. This led to her being kinda harsh and mean. And, after finding a forbidden book, containing all kinds of wonderful(to her) spells, she started going into growing and rampaging cities. And with the spells she has learned, she reverses time whenever she's done, so it seemed like nothing happened. She has also used this spell to become insanely rich, living in a huge mansion between Canterlot, and, has her parents working for her for a slaves pay.
