NORA: "You might give me money, Torvald. Then I will wrap it up in beautiful gilt paper and hang it on the Christmas Tree." (1.38-1.40)
There's a good chance that Nora wants money for Christmas just to pay down her secret debt.

NORA: "Christine! It will be splendid to have heaps of money and not need to have any anxiety, won't it?"
Nora seems to show very little sensitivity to her friend's financial problems.

HELMER: "I hear [Krogstad] is a good worker, too. But I knew him when we were boys. […] this tactless fellow lays no restraint on himself when other people are present. On the contrary, he thinks it gives him the right to adopt a familiar tone with me." (2.117)
Looks like Torvald has been hiding something as well. This is the first time he mentions that he used to know Krogstad.
