When did you stop throwing balloon parties for your birthday?

I know where you are coming from I think I was about that age when I got embarrassed about the idea of having a "kids" birthday party and I wanted to do more grown up things like go out for a meal or go see a film for my birthday. Of course now I have completely regressed. I turn 20 this year and I'm going to be having a Disney themed fancy dress party! Complete with balloons of course!!
