The exchange between Snowden and Yossarian in "Catch-22" highlights the vulnerability and fragility of human emotions in dire circumstances. Snowden’s repeated, childlike plea of being cold signifies not just a physical sensation but a deeper sense of fear and helplessness. Yossarian's reassurances, though well-intentioned, reveal his own uncertainty as he struggles to comfort the wounded young man, embodying the confusion and absurdity of their situation.

This poignant moment underscores the themes of war's dehumanizing effects and the often inadequate responses to individual suffering. Yossarian’s simple phrases, "There, there," reflect a futile attempt to alleviate Snowden's pain, showcasing the difficulties in confronting the horrors of battle. The repetition of "I'm cold" serves as a haunting reminder of vulnerability in a world where compassion can feel insufficient.
