Every survivor is special. Each represents the triumph of life over death and over evil. The memories they have had to live with are, thank God, something the rest of us are spared.
For some, those memories have been simply too much. But for others, the determination not to be defined by their suffering led to lives of remarkable optimism.
No one exemplified that spirit more than Lily Ebert, who died at the weekend having, quite wonderfully, reached the age of 100.
She may have been a centenarian but her spirit seemed to be that of a young girl. In recent years her insistence that she had a duty to tell her story led to her becoming a global force on social media, most notably reaching a young generation on Instagram and TikTok.
