I do the decorations and the lights, and find a nice variety of Christmas music (hint: The more you censor, the less variety you are going to get). Even though I believe that jesus is hogwash intended to enslave the world, I take it as "the sun" when they mention Christ. I would rather actually worship the sun on that day.
But, I do not take extremes in going into debt. That will only hold you back next year, making next Christmas dreary. I would just as soon stay within my means so I can keep doing it year after year without worrying about it all year long. And I would rather be getting things to prepare for it during July and August, so there is plenty of time instead of that mad rush on December 24 when everything should already be ready to go. Even food--I would rather buy non-perishable items slowly during the fall and stay within purchase limits (and, even in absence of such, within reasonable quantities) and have the time to get items in short supply instead of panicking the day before.
And, above all, I do not advocate drink driving. Those who do that are idiots, especially since every year hundreds of thousands are warned and still drink and drive, and tens of thousands (including other road users) die from drink driving (plus many others seriously injured). Drink and drive, and you are asking for a dreary Christmas and a crappy new year (especially if you kill or seriously injure someone or get badly hurt yourself). That is one thing I say Bah! Humbug! to.
