The quote from Cecelia Ahern's "P.S. I Love You" speaks to the inevitability of life continuing despite personal struggles. It suggests that individuals can feel isolated by their challenges, yet the world operates independently of one's circumstances. This reality can be a source of comfort or despair, depending on one's perspective.
The image of an insurmountable bubble illustrates the desire for protection from life's hardships, but the quote emphasizes that no such barrier exists. Ultimately, embracing the continuity of life may be necessary for growth and resilience in the face of adversity.
