There are only two ponies not joining in on Rainbow's break down. One's a stoic, so the reason is obvious. But what about the Princess of Friendship? Isn't empathy in her job description? And not a single tear.

Yes, I know it's late. As always, your criticism and praise is welcome in equal measure. I do mention shipping, but I think you'll quite like it.
There's also a tiny bit of swearing because in my head canon Twilight would use it for the sake of hyperbole.

I have a video review! Yes, I did watch it, Yes, I know it says don't read it, and frankly you should listen to him! YouTube
Frankly I'm surprised anybody thinks this is good. As mentioned in a tiny blog blurb, I don't plan on revisiting this story because I have other terrible crap to write. I'm sorry for subjecting the internet to this.
But if you think this is bad, just be grateful I don't publish the droll I wrote in High School.

For a long time, Twilight and Rainbow Dash have been marefriends, and as time passed on, their love for each other kept on growing.

With her recent ascension to an alicorn, Twilight recalls the longtime pegasi tradition of feather gifting and wishes to bestow one of her own to her special somepony. After much preparation, she sets off on her next date with Rainbow, hoping that her lover will accept her gift.

A simple fic written as a belated birthday present for that jerk my friend, Twilight the Pony.

In the warmth of her cloud home, Rainbow Dash is about to turn in for the night when she hears Scootaloo crying outside in the middle of a vicious blizzard. Plucking the freezing filly from the snow, Rainbow hopes to provide some much-needed comfort for the otherwise tough young pegasus, but she uncovers a disturbing reality that she knows she cannot handle alone.

Knowing only one pony that could really help her out, Rainbow enlists Twilight’s help, determined to set things straight for Scootaloo. But what Rainbow doesn’t know is that in her efforts to provide a better life for the filly, her friendship with Twilight will develop into something more.

Fearing the consequences of her actions in the bipedal world, Sunset Shimmer returns to Equestria and moves to Ponyville where Twilight Sparkle can keep an eye on her. Sunset Shimmer, bored and beaten, casts about for something to distract her, but soon the feelings growing inside her for Ponyville's princess can no longer be ignored. Nervously, with a little help and encouragement, Sunset begins to open her long-frozen heart to Twilight Sparkle, but when the shadows of Sunset's past threaten to destroy any chance of her happiness in the present, Sunset and Twilight may have to risk everything they have and defy cosmic forces older than Equestria in order to seize their fragile chance at happiness.

Many thanks to pre-reader The Albinocorn, but don't blame him for any errors you might find in the first chapter, because he only became pre-reader after I posted chapter 1
