Answer:
“TRUE! --nervous --very, very dreadfully nervous I had been and am; but why will you say that I am mad?”
Explanation:
According to the excerpt from "The Tell-tale Heart", the narrator tries to convince the readers that he is not a mad man, even though his words and behavior seem to prove otherwise.
The narrator asserts that although he is nervous, he isn't a madman and it is buttressed in his statement where he said, “TRUE! --nervous --very, very dreadfully nervous I had been and am; but why will you say that I am mad?”
