I've spent the last dozen or so Christmases alone, as with the vast majority of my birthdays. I don't let it get me down, but choose to enjoy the solitude. I'll drink my beer and watch my movies. One thing I really enjoy is just stepping outside late Christmas Eve and going for a walk–the quiet is almost surreal. I treat myself to homemade pizza. But it's also well known that nothing cheers you up more than helping some one else less fortunate.
