In Jonathan Lethem's "The Fortress of Solitude," the narrative reflects on fleeting moments and simple actions that may seem significant but ultimately fade away. The mention of a hydrant, rarely opened, evokes the idea of lost opportunities and the fleeting nature of summer, highlighting how time passes quickly without leaving a lasting impact. The reference to spraying water through a car window suggests playful but transient memories that do not define the summer experience.

The character Dose's indifference to flying symbolizes a broader theme of unattainable ambitions and the reluctance to engage with aspirations. Flying represents possibilities that are deferred, much like summer itself, which is filled with whims that come and go. Ultimately, the text suggests a longing for more meaningful experiences in life's brief moments, emphasizing the contrast between fleeting joys and deeper desires.
