In Nick Hornby's "Funny Girl," the protagonist, engaged to Edith, is blissfully unaware of the potential loneliness that marriage can bring. At that moment, he is consumed by love and optimism, unable to envision any romantic challenges that might arise in the future. His focus is on the joy and excitement of their engagement.

This optimistic outlook contrasts sharply with the reality of marriage, as the protagonist would later discover. The quote emphasizes the naive hopefulness that often accompanies engagements, revealing how unforeseen feelings of isolation can emerge, even amidst love and companionship. This highlights the complexities of romantic relationships beyond initial happiness.
