This story is a sequel to Bid Time Return
It's nearly Hearth's Warming, and Foggy Freeze is ready to relax, ready to retire, ready to enjoy the holiday with his wife and children.
He is not ready for Discord to pop up at his desk unannounced.
And truth be told, Discord is not ready for this either, but Fluttershy did ask him to apologize to her father, and what better way to celebrate the holidays with an attempt at a much better second impression?
