Fluttershy warily watches Pinkie dart from one furniture piece to the next. She loves her marefriend to bits. But sometimes, when the stars align something happens to the bouncing bundle of joy. It might be some other cosmic event she doesn’t know about, and she's always very sorry if she’s gotten it wrong.

Pinkie becomes silent for hours on end, looking at Fluttershy or staring off into the distance. Sometimes she comes up to Fluttershy and whispers things like ‘the coast is clear’ before kissing her right on the lips.

So it not a bad thing. Most of the time.
