A big leather-bound volume makes an ideal razorstrap. A thing book is useful to stick under a table with a broken caster to steady it. A large, flat atlas can be used to cover a window with a broken pane. And a thick, old-fashioned heavy book with a clasp is the finest thing in the world to throw at a noisy cat.
I make films about people with disabilities as well and I think this question is more relevant in regards to these documentaries where the actual person appears on film. I know these people are proud of who they are and what they are doing with their lives.
