Newlyweds become oldyweds, and oldyweds are the reasons that families work.

The line plays on the rhyme of “newlyweds” and “oldyweds” to compress a generational story: marriages begin with novelty and romance but, if they endure, mature into long-term partnership. The second clause suggests that stable, lasting couples provide the emotional and practical backbone of family life—modeling commitment, creating continuity, and often serving as mediators, caregivers, and keepers of shared memory. It implicitly values longevity over spectacle: the wedding is a moment, but the marriage is the infrastructure that makes a family resilient. The tone is affectionate and proverbial, typical of anonymous “family sayings” circulated in cards, speeches, and compilations.
