what comment does mademoiselle reisz make about robert, and how does edna react to her comment

Mademoiselle Reisz then shows her the most recent letter from Robert. She admits that Robert does not know that Edna sees his letters and that the reason he does not write to her himself is that he loves her. As Mademoiselle Reisz plays the piano, Edna reads the letter and shrieks with joy when she discovers that Robert is coming back to New Orleans very soon. Mademoiselle Reisz asks Edna if she is in love with Robert, and for the first time, Edna admits that the answer is yes. When she is asked to explain why, she cannot; she just does. Overwhelmed with joy, Edna leaves Mademoiselle Reisz and then proceeds to send her children a large box of candy and to write a very friendly letter to her husband.
