In "Speedboat," Renata Adler portrays a group of girls who frequently find themselves short on money, particularly for expenses like taxi rides and late-night food deliveries. This financial struggle leads them to borrow from one another not only cash but also experiences and interests that enrich their lives. They rely on each other for support and inspiration in various forms, reflecting a sense of community and camaraderie.

The borrowing in their lives transcends monetary transactions; it includes shared passions for literature, music, and spirituality. Just as previous generations might have exchanged clothing, these girls exchange cultural and intellectual influences, creating a tapestry of connections that define their experiences. Through this lens, Adler illustrates the complexities of friendships and the ways in which people impact each other's lives profoundly.
