標題：Cohabitation in Modern Society

In modern society, cohabitation has become increasingly common, with many people choosing to live together before getting married. This trend has many benefits, such as saving money on wedding expenses and planning for a future together sooner rather than later. However, cohabitation also has its challenges, such as managing household chores and financial responsibilities equally. Despite these challenges, cohabitation can be a healthy way to build a relationship and prepare for marriage. I believe that cohabitation should be an option for everyone, regardless of their religious or cultural background.
