For All We Know

The speaker addresses someone they love while recognizing that they are still partly unfamiliar to each other. They believe they have many years to share and learn, but they do not assume that closeness or understanding is already complete. The mood is gentle and hopeful, with a note of patience: the relationship’s future will become clearer as they spend time together.

The phrase “strangers in many ways” suggests that two people can care for one another and still have much to discover. “A lifetime to share” presents love as a long process, not a finished achievement. The idea of taking a lifetime to say “I knew you well” implies that truly understanding another person may take many years.

The repeated thought that “time alone will tell” leaves the outcome open. The speaker hopes love may grow, but does not promise that it will. “For all we know” means that this is possible, though not certain. Overall, the lyrics can be read as both a tender expression of confidence and a modest admission that love depends on what the future brings.
