What does the expression "Two a dem is one age" suggest about two individuals?

The expression "Two a dem is one age" suggests that the two individuals are very similar or alike in nature, characteristics, or mannerisms. In this context, the use of "one age" indicates a sense of shared experiences or similarities that go beyond mere friendship or familial ties. It implies that the two share a bond that makes them appear almost indistinguishable from each other in certain aspects, highlighting their likeness rather than their relationship status or personal interests. This reflects a cultural understanding of how closely people can be associated with one another through shared traits, behaviors, or a collective identity.
