This poem by Abse expresses nostalgia for his childhood home of Cardiff. As he returns to the city as an adult, he finds that it has changed significantly and no longer feels familiar or like home. The river that had seemed large in his memories is now just a stream. His childhood memories are fading and unclear. The city is now filled with strangers and feels alien and bleak compared to his recollections. Revisiting his hometown highlights how much he has changed and how his childhood cannot be regained. Though he feels nostalgia, in the end he is only able to leave his past behind and continue on his way.
