Her generosity is unmatched. She is a fashionista with a heart of gold. Rarity is good at what she does. When it comes to clothes she is a true artist, but like all artists - she has her own curse.

Solitude was her demon. She never let it show, and her plethora of friends made it easier for her to hide her pain. But somehow that defense broke. Even with Twilight, Fluttershy, Pinkie Pie, Rainbowdash, and Applejack, she still managed to snap back into fits of tears. But why?

For Sweetie Belle, having a babysitter is not that big a problem, especially when her babysitter is the element of magic herself. When Twilight devises a spell to help her with her apparent problems, however, both of them will have to learn a lesson that won't soon be forgotten.

Now has a sequel called Sizable Differences

Enjoy.
