Ah yes, Birthdays. When we are younger, we may very well hope for them (Especially when it signifies that we can now legally drink). However, even at this comparatively young age, I am starting to understand how they may begin to be looked upon as little more then a mark of the passage of time . . . Luckily for you however, it would seem that Alcohol acts as a preservative; leaving you with the benifit of growing wiser (Or so we would all like to believe) as you mature: Without having to suffer any of the deficiencies common with ageing (I suspect that you are actually a Witch).
Even as the inevitable occurs, I hope that you will continue to at least stay young at Heart. Happy Birthday Mia. Now go out there and make your memory of this day a fuzzy one!
