The Reason for the Season (Horde):

Speak with Sagorne Creststrider in the Valley of Wisdom of Orgrimmar about the Feast of Winter Veil.

Furmund: Gifts, treats, presents... bah, I say!

Those goblins pollute the true meaning of this season - the Feast of Winter Veil. This is a time of renewal; the land slumbers under a blanket of snow brought forth by Greatfather Winter, who is NOT the bumbling fool over there in the red suit!

If you're interested in learning what the Feast is all about for yourself, ask Sagorne Creststrider. I'm sure he'll be surprised that someone cares about history rather than getting presents.

Sagorne Creststrider: Do you have the spores, Weegee? There is a concoction I must send to my associate in Thunder Bluff, which requires the spores...

Sagorne Creststrider: The Feast of Winter Veil, you say? Alas, in times past it held a more substantial meaning to us tauren. Nowadays, it seems as though others have turned the legend of this season of renewal into something that helps to sell candies and presents.

It's no surprise that Furmund is bitter about that sort of change. He and other tauren like him cling to our past like a banner of war. While I think a little celebration is always good, it is important to remember the origins of the Feast.
