What are some examples of verbal iorny in tell tale heart?

In the short story Tell-Tale Heart, the narrator mentions that he plans on killing the old man. He goes on to say, "During all of that week I was as friendly to the old man as I could be, and warm, and loving" (Poe 2). This would be considered verbal irony because the narrator is anything but loving and warm.

i would say the correct answer is not concrete.
