Cassandra

The speaker describes a relationship that feels deeply real and comforting, even though he cannot quite explain the feeling. He values Cassandra’s faithfulness and the love she gives him throughout the day, especially when he feels lonely. The repeated encouragement to “ride on” gives the song a warm, buoyant feeling, as if he is urging her to keep going—or celebrating their relationship as it continues.

“Something deep down inside” suggests an emotion felt strongly but difficult to put into words; “cannot tie” may mean he cannot define or explain it. Feeling “blue” is an idiom for feeling sad, so the speaker says Cassandra’s affection keeps loneliness from turning into sadness. The morning-and-evening image emphasizes that her care is steady and present at different times, rather than occasional.

The song presents love through simple claims of trust, comfort, and constancy, not through a detailed story. “Ride on” could be a cheerful refrain, a wish for Cassandra to carry on, or a broader image of moving forward together; the lyrics do not settle on one meaning. His confidence that she has “never been unfaithful” is also qualified by “as far as I can see,” leaving a small note of uncertainty beneath his gratitude.
