I went on a birthday lunch today. The birthday girl is a big party animal and has had lots of different celebrations exactly as she did 10 years ago. That's her thing and I'm happy to celebrate with her. But for mine I don't want cards with my age on, banners or balloons. It's the same to me as one ending in 9 and the next one ending in 1. I'm sensitive about people knowing my age (obviously my friends know) and I don't want to advertise in this way. Certainly not in public.
Another friend repeatedly called me miserable. I don't think I am, I always do things for my birthday and invite them all. I'd be mortified if I was presented with balloons and banners.
