Explanation:

Katherine Mansfield wrote this short story titled "The Doll's House" to clarify that marriage should join equals and not masters and minions.  This agrees with the view that friends should marry and not strangers who do not know and respect  one another.  The story encourages the dissolution of any marriage which is not based on equal rights for the partners.  It condemns people's misunderstanding of what marriage is all about.  Marriage is a relationship based on love.  It is not a contract of convenience or trade of some goods.
