On the eve of her 50th anniversary, Applejack reviews her "scrap table"--some of the small, stupid, inconsequential, yet supremely important things that have helped her relationship with Rainbow Dash become what it is. It certainly hasn't been easy, and the effects of their relationship have gone far beyond Ponyville proper, but one thing is for sure:
She regrets none of it.

Originally supposed to be a part of AppleDash Collab number two, but it kindof crashed and burned died, with mine being the only entry (who says ADD is a complete curse?). I decided I'd post what I had in the AppleDash Prompt Tag, but then realized, it's over two thousand words. It might as well be its own submission.
And so now it is.
Now, the rules of this collab were, pick a pony and pick a random item, and write a flashback on how it affected their relationship / brought them together / helped them through a tough time / saved Equestria / that sort of thing; hence the chapter name.
They're all out of order and very random; but isn't that how all memories are?
