There is a quiet mythology around eldest daughters, whispered at weddings and inside living rooms where relatives speculate on who “makes the best spouse.” She is the one people describe as mature, dependable, sacrificial — a natural caregiver who grew up rehearsing adulthood long before her peers.

They didn’t become ideal partners through magic; they became them through labour. And when the world calls them “the best spouses,” it often forgets that what looks like compatibility is sometimes just conditioning.
