Relationship Between Mrs Linde and Nora Helmer

Mrs. Linde is the most functional character in terms of plot development, as by having her in the play serves as a way for Nora to tell the audience of her 'other' life.

Immediately you see two main differences between Nora and Mrs Linde, not really in their characters but in their relationship/marriage roles. Nora and Torvalds relationship appears to be very typical of that era. There is no fairness in their relationship, with Torvald controlling everything Nora does. Nora's most important role is to please her husband and Torvald considers himself superior to her by calling her names like "skylark" and referring to her as "little" which is diminutive, whereas the relationship between Mrs Linde and Krogstad is much more open and equal.

They both, however, have the unselfish personality trait as they have both made major sacrifices to protect the ones they love. Nora - taking out a loan secretly to save her husband and Mrs Linde - refusing her love (Krogstad) marriage proposal in order to keep her family happy. This lead her to being so submissive and not being able to have her own mind, which she hated.
Nora also is in a marriage that is very domineering which she also wishes to escape.

The occurrence of a wife leaving her husband to become their own individual was very rare, almost unheard of, and certainly frowned upon in that day and age, therefore for two women to be going through exactly that, or been through that and to know each other is extremely rare which also shows their likeness.
