" Around this time, I was again tested for partial deafness, for although I could speak I often didn't use language in the same way as others and often got no meaning out of what
was said to me. Although words are symbols, it would be misleading to say that I did not understand symbols. I had a whole system of relating that I considered "my language." It was other people who did not understand the symbolism I used, and there was no way I could or was going to tell them what I meant. I developed a language of my own. Everything I did, from holding two fingers together to scrunching up my toes, had a meaning, usually to do with reassuring myself that I was in control and no one could reach me, wherever the hell I was. Sometimes it had to do with telling people how I felt, but it was so subtle it was often unnoticed or simply taken to be some new quirk that "mad Donna" had thought up. "
