Everything that's born has to die, which means our lives are like skyscrapers. The smoke rises at different speeds, but they're all on fire, and we're all trapped.
The quote conveys the inevitability of death, suggesting that life resembles skyscrapers where each person experiences their journey at different paces. Just like buildings can catch fire, our lives are filled with challenges that can be overwhelming, highlighting the transient nature of existence.
Foer’s metaphor implies that, regardless of the differences in our experiences, we are united in the struggle against life's challenges. The notion of being "trapped" indicates a sense of urgency and the shared human condition, encouraging readers to reflect on the fleeting moments of life and how we cope with our mortality.
