C.S. Lewis, in his book "A Grief Observed," reflects on the profound impact of loss and grief in a deeply personal way. He articulates how the absence of a loved one creates a pervasive sense of emptiness, much like the vastness of the sky that envelops the world around us. This metaphor highlights how grief permeates all aspects of life, affecting thoughts and emotions, and serves as a constant reminder of the lost relationship.

The comparison underscores the overwhelming nature of grief, suggesting that, just as the sky is inescapable and covers everything, the absence of a loved one affects all experiences and moments. This poignant observation captures the essence of mourning, illustrating how love and loss are intertwined and how the memory of the departed continues to influence the grieving individual's journey.
