The poem reflects a poignant moment shared between two individuals on an old bridge at twilight. As they reminisce about a fleeting train that passed by, the speaker questions whether this moment will remain etched in their memories. The serious response from the other person underscores the significance of their experience together, highlighting the emotional weight of their connection.

As the night envelops them, they experience a profound sense of longing and shared history, suggesting that this moment transcends time itself. Both the imagery of the bridge and the mention of crying evoke themes of nostalgia and the ephemeral nature of life and relationships. Ultimately, it suggests that their bond is a lasting testament to shared memories, even in the face of time's passage.
