I think we each do it in different ways. Mostly I do it by attending demonstrations, writing to politicians and key figures, and spreading information to people who aren't aware of some or a lot of what disabled people are up against. That includes disabled people who, by luck or whatever, get their benefits and help with no difficulty and don't realise how much unfairness there is in the system.
So whilst I think it's a great idea to use a drama for disability awareness raising, and whilst from my own life I know how frustrating it is if you want people to join you in a project and it's not their thing, I hope, Bule, you won't think the worse of Ouchers who don't feel they've anything to contribute.
For my own part, I've never written or produced a drama and I hope that suggestions I make are realistic. I shan't be offended if my suggestions turn out not to be what's wanted.
