In my country, moving out is synonymous with marriage. That is the only time a girl leaves her home for good. No other reason is acceptable for a girl to be “moving out” from her home. Which is why, in my country, marriage is a bigger deal than it is in the books I’ve read all my life.
For a fact, marriage comes with alot of drama. Whivh is why it is ever so surprising when people willingly gey into it. Now the thing is, there is no other way a girl can move out of her home without marriage,and you can imagine the frustration simmering in her come age 25 or so.
Bcuz whatever country or religion it might be, parents will be parents. Kids will be kids. And adult kids in the home will be frustrated.
