Hi. You have not shown the text your question refers to, which makes it impossible for you to answer it. However, when searching for your question on the internet, I was able to find another question exactly like yours, which showed that an excerpt from the play "A Doll's House."
This excerpt depicted the moment when Nora had just finished shopping for Christmas and was excited about all the products purchased. Torvald, on the other hand, was somewhat annoyed by the amount of money spent on the products and this is reinforced by the stage directions, which show Torvald's apprehension upon seeing the numerous packages of products.
Stage directions are instructions given to actors to direct them as to how they should go about representing the characters' emotions and sensations. These instructions are added to the text usually within square brackets or parentheses.
