Ah yes. The christmas ad that has nothing to do with christmas. There's also a fish dish the wolf makes... great attention to detail there.
It is all about Christmas and New Year: cooking good healthy food for the extended family, and new year's resolutions.
The ad illustrates the Christmas spirit and fish is a Christian religious symbol and actually traditional at Christmas in some countries and areas. I don't know if they did it on purpose in this ad or just because it would obviously not have worked for the wolf to bring a meat dish.
The family were sitting around the table eating dinner while the kids was getting a story read to him about the present he just received. Nothing Christmasy about that at all.
