Answer :
The sudden silence of Nora and her request for Helmer to coach her indicate that she is feeling uneasy and concerned about something, according to the passage.
Since she doesn't want Helmer to read any letters or be preoccupied with anything "horrid" prior to her dancing performance, it also appears that she is keeping something from him.
The best guess for what Nora intends to do is to perform a dance that is significant to her and calls for coaching and focus, potentially in a public environment. The dance seems to be a big occasion that Nora is very worried about, yet it is unclear what it is for or what is at stake.
There is considerable friction between them despite Helmer's willingness to support Nora and his assurances to coach her due to his suspicion that Nora may have a letter from someone she does not want him to read.
