Flurry Hearts childhood was different.
Her parents saw her as the next Princess.
The big Ruler of the crystal empire, but extremely ignoring the wishes of their daughter.
She didn't want that.
She was forced to be a Princess, by her parents.
While she wanted to play with her beloved Brother, her mother screamed at her.
"a princess should this… a princess don't does this..", all sentences her mother repeatedly said to her.
That ended into Flurry hating her Parents, or just her mom.
Shining was after all not there.
He traveled all across Equestria, and even Cadence would travel with him.
Leaving their kids at auntie Twilights house.
The only happy Place for Flurry was Ponyville.
