The quote from Darren Shan's "Sons of Destiny" reflects on the way adults perceive their childhood memories. It suggests that people often believe they can remember their true selves as children, but this is an illusion. The idea is that no matter how much one looks at old photos or videos, these images fail to represent the genuine essence of who they were at that time.

Additionally, the author hints at a deeper connection to the past that cannot be accessed through mere visual aids. To truly understand one's childhood self, one must engage more intimately with those memories and experiences, implying that a simple nostalgic reflection is insufficient to grasp the complexities of one's earlier identity.
