I find it fascinating to think about what the world is going to be like when people won't talk anymore.
Plays are so much more special if they've never ever had a production, but I think you can really work on a play and make it better with each production.
What I loved about the acting class was that you got to think all day long about a person that wasn't you, and figure out why they were sad and what they wanted, what they dreamed.
