what does the christmas tree symbolize in a doll's house

The Christmas tree is a symbol of the holiday season, but in "A Doll's House," it is also a symbol of Nora's desperation and unhappiness. The tree represents the illusion of a perfect family life that Nora has created for herself, but it also symbolizes the lies and secrets that are tearing her marriage apart. The tree is a reminder of how much Nora has given up in order to maintain the appearance of a happy family life, but it also represents the limits of her freedom and independence.
