Applejack and Sprite always had a strong bond. They knew almost everything about one other, even private things.
Applejack would often wait in the kitchen for Sprite as she sleepily staggers into the room in the mornings, sometimes teasing her about the often soaked padding that clung to her rear end.
She also knew that traveling wore heavily on the poor girl, so a few days of long sleep would still leave her cranky in the morning. She didn't mind it though, Applejack thought it to be rather cute.
