I'd advise readers to try to avoid excess that they'll regret the next day, but that's not behavior that I've exhibited much in my life.
Besides, if you're going to regret, I believe it's better to regret what you've done rather than what you didn't do.
I spent the early hours of this morning speaking with a Finnish guy claiming to be Santa Claus. He certainly looked the part, beard, red suit, and all. There was also a girl in the place done up as a red-nosed reindeer. I hadn't drunk enough that there's any doubt that they were real, either.
