I celebrate my birthday (and often the birthdays of my friends) as the priority holiday in any year.
After all, you've made it one more year. You're still here, you're healthy (you hope,) and you have the exciting possibilities of the future ahead of you.
I almost always make myself an extravagant cake - even if someone buys me one at the Bonbonerie. I take the day off from work, sleep in, have sex if I can - even in bachelor times such as these - maybe go shopping, go out to dinner with friends after fixing myself a favorite lunch. I usually go for a run AND do some yoga.
I start the day with Madonna's Holiday
I could go on. I love birthdays. I'd skip Christmas for a birthday (I know I know it's a birthday, but whatever.)
Mine's actually a week from today. 30whore as Zim says. LOL Woot!
