The quote "And nobody had told them that they were short on time" from Cecelia Ahern's book "P.S. I Love You" captures a poignant theme about the human experience and the often-unnoticed urgency of life. It suggests that people may live their lives unaware of the limited time they have, leading to missed opportunities and unspoken words. The realization of time's constraints can prompt deeper reflection on relationships and the importance of expressing love and appreciation before it's too late.

This message resonates with readers as it highlights the value of living in the moment and cherishing connections with others. It encourages individuals to be proactive in their relationships and recognize the fleeting nature of time. Ultimately, Ahern’s narrative emphasizes that awareness of our temporal limitations can enhance our appreciation for the present and the loved ones around us.
