Final answer:
Gordon remembers his friendship with Chris with nostalgia and restraint, exemplified by their walks together and a masculine avoidance of emotional display. Their bond is appreciated but complex.
Step-by-step explanation:
After Chris and Gordon part ways, Gordon experiences his friendship with Chris with a sense of nostalgia and restraint. Despite their shared aversion to educational institutions, indicated by Chris's pursuit of intellectual interests outside the mainstream system and his focus on the Cognitive Theoretic Model of the Universe, they still valued their companionship.
This is exemplified in their habit of taking long walks without the need for much conversation, demonstrating a masculine type of friendship that shuns overt emotional displays. When they reconnect, there is a tangible sense of reservation, seen in the quote, "It's good to see you—I guess," conveying the underlying appreciation for their bond but also highlighting the complexity of their relationship post-separation.
