People say that time slips through our fingers like sand. What they don't acknowledge is that some of the sand sticks to the skin. These are memories that will remain, memories of the time when there was still time left.
― David Levithan and Andrea Cremer, Invisibility
Despite any issues I might have with this book, it has some amazing quotes. This is definitely, I feel, one of the most poignant. One of my favorites.
