Quote context

- I have come here today expressly to ask you what you think of our youngest, Algernon.

- A sweet, well brought-up child.

- Algernon thinks so highly of you, that he has begged me to come and ask you to give him private lessons.

- That's very flattering.

- Yes, I am deeply honoured, madam.

- Excellent.

- You will come to my house tomorrow evening, and you can tell me then what you've decided about the number of lessons required. And the price.

- Certainly, madam, certainly.

- I may as well tell you now when I'm free.
