I kind of hate birthdays. I don't like being in the center of attention in that way (on the other hand, I have dressed rather extravaganlty for years to say something) for something that was not my achievement. I do believe there's more of us and not liking birthdays -and especially the celebrations - is perfectly normal.

I must admit that I don't hide my birthday on facebook though and I do enjoy the wishes I do recieve from a few close friends. It's all fine as long as I can skip on the cake and songs. And when I did do something for my birthday, I would take a day off and visit a museum or go mountainbiking (or both on the same day) on my own. All this just to say there's a lot of gradations of not liking your birthday ...
