I don't really celebrate, as I've already reached an age where I prefer not to think about my birthday, because I'm getting older and I don't like it, haha. I stopped celebrating when I hit 21 and suddenly realized that I couldn't cling to any vestiges of imagined childhood. I might go out and watch a movie if something is on, and maybe I'll buy myself a couple of things before/after in town because presents, but otherwise it's pretty much a normal day for me...only I'm older. Sigh. There's usually a cake in there somewhere, too. A jam and buttercream sponge. The buttercream is very important. Have you ever tried a sponge with jam but without buttercream? It's horribly dry. There are also candles I have to blow out, singing I have to endure - which are the most painful three minutes of the day - and a wish I have to make. Every year I wish I was a year younger instead of a year older.
Speaking of...I do let other people make a fuss over me if they absolutely have to; it's not entirely doom and gloom. Acquaintances always seem to feel obliged to wish me a Happy Birthday; I get a sudden onslaught of messages on Facebook from people I barely remember, and people I've not spoken to in months (sometimes since my last birthday) might message me as well through the usual channels for them; Skype, Forum Private Message, E-mail, etc etc. Relatives phone as well, usually in the evening. It's all very...tiring. But if it makes them happy, it's fine...doesn't cost me anything to say thank you, and it's nice to be thought of. I don't smile, though. It's my birthday and I'll sulk if I want to. If asked why by older people, I tell them I'm one year closer to their age. If asked by younger people, I'll tell them they'd sulk too if they were my age. It all works out.
Really, my birthday is more an excuse for other people to celebrate than me, now. Celebrating that I'm another year closer to death, probably. xD
