Every day, it was the same thing.
Get up, board Cid's airship, fly around to different towns, asking about Sephiroth.
That was the normal routine.
For Yuffie, it was something more akin to:
Get up, whine, complain, procrastinate, get dragged aboard the airship by the rest of the group, hide in her cabin, and try not to lose her breakfast (it was the most important meal of the day, after all).
Then when they land in a town, she runs off of the ship, leaping and yelling for joy, and then heads for the nearest restaurant, intent on eating everything she could get her hands on.
But by the end of the day, after her bad mood and airsickness has dissipated, and she's eaten all that she can, there's only one thing left to do.
"Goodnight, Vinny."
"…Goodnight, Yuffie."
