The quote "You don't miss things. You miss people," from Mitch Albom's book "The First Phone Call from Heaven," emphasizes the emotional connections humans have with one another. It suggests that in the grand scheme of life, material possessions hold little true value; rather, it is the relationships we cultivate that leave a lasting impact. The sentiment encourages readers to cherish the connections with loved ones, highlighting the importance of community and support in navigating life's challenges.
