What if only Sadness fell from the emotion's headquarters and Joy stayed above?

(AU fanfic) She could only imagine how Fear, Anger, and Disgust would react to her newfound feelings. None of them would ever expect the most mellow of the emotions to verbally tear the happiest. But Sadness was through being a pushover, and Joy needed to stop being such a happy thorn in Riley's palm.

It was rare for Joy to actually TELL Sadness to drive. (Part 3 of the Whimsical Affinity series. Written pre-movie, though you might still want to avoid this if you're steering clear of spoilers.)

It's been 6 years since Surprise, one of the Emotions, died. One day, Sadness begins to wonder what happened that day anyways. She decides to go around asking questions to the other Emotions (particularly Joy and Fear) to find out what happened that day. Please note that this was published before Inside Out came out, so this might get very AU depending on how that movie goes.

Happy days turned into happy years turned into a happy life. But now it's all over, and the emotions have to say their farewells. Warning: keep tissues handy.
