In Mitch Albom's "The First Phone Call from Heaven," the protagonist experiences a transition in emotions after a moment of joy. Initially overjoyed, she finds herself grappling with a profound sense of sadness. This shift in feelings is surprising and aligns with the complexity of human emotions, where happiness can be intertwined with a sense of loss.

The unexpected sadness she encounters suggests that even moments of elation can lead to deeper reflections on life, love, and mortality. This exploration of emotional depth showcases how joy can sometimes highlight the fragility of happiness, leading to feelings of depression when one realizes the temporal nature of such bliss.
