Comedy is more difficult than drama. I think it's really difficult to make someone laugh because people have very different comedic sensibilities. In drama, you can get away with being a great actor and surrounded by great actors and having good writing. But in comedy you have to listen and you have to perform with a certain rhythm, because if you don't, it's like playing a wrong note in the orchestra and you can hear the off key and it will fall flat and you won't get that instant response.
When I say that I can write nothing but weird fiction, I am not trying to exalt that medium but am merely confessing my own weakness. The reason I can't write other kinds is not that I don't value & respect them, but merely that my slender set of endowments does not enable me to extract a compellingly acute personal sense of interest & drama from the natural phenomena of life.
An interesting play cannot in the nature of things mean anything but a play in which problems of conduct and character of personalimportance to the audience are raised and suggestively discussed.
