Deaf Theatre?

Something else that has happened since starting my internship has started me thinking about other possibilities with theatre. I am staying with my aunt, uncle and 3 cousins during the summer, and this past week had the chance to see the school where my aunt teaches and meet some of her deaf students, including one deaf/blind student she's been working with for the past few years. Seeing these students sitting in an assembly, the way they interact with the teachers and each other, and through many conversations with my aunt I've been thinking a lot about deaf theatre. I've always had some of an interest in learning sign language, as many of my little cousins learned it from my aunt before they could talk. I know some basic signs, but have never took a class or managed to learn more. Meeting so many of these students, especially after seeing the sign language interpreter at Number the Stars, I just can't get the thought of deaf theatre out of my mind. I've begun doing some research into how it works. I found the website for the National Theatre of the Deaf, and am pretty amazed. This is definitely something I'm going to keep researching and maybe even start learning more sign language this summer so I can decide if it's really something I want to look more in to.
