You might say something like:
The narrator's state of mind is characterized by a sense of nostalgia and regret, which is supported by their detailed observations of the carts and what they represent from the past. For instance, the narrator reflects on the "scuffed wooden wheels" of the carts, indicative of their frequent use and the memories attached to them, highlighting a longing for a time that has since passed.
