Just to add to the confusion...

not only do I not know how old I am, I'm also no longer sure when my birthday is! One friend texted me a happy birthday message yesterday (it's so unusual for him to be early, I wonder whether it was actually a very very late message from last year?!), then had Happy Birthday sung to me along with a card and cake at church today. Whereas it's not my actual birthday until the day after tomorrow, and my party's two days after that! So I'm obviously spreading the fun out as long as possible...I need something to cheer me up!
