What does it mean? You can find it on page 317, where he describes himself.
What does he look like? I don't understand.
In this fascinating novel, Death is personified and directly addresses the reader. This chapter is Death’s diary, and when he suggests that the reader look in the mirror he is reminding us that the human race is what caused the destruction. During World War II, Death is feeling grumpy. He is busy and overworked, because of the combination of war and the genocide of the Holocaust.
Death is also grumpy because he feels misunderstood. He notes that the reaper image of a robe and scythe is inaccurate (he only wears a hooded robe when it’s cold). Death points out that he looks just like us.
“On the other hand, you’re human. You understand self-obsession.” (p. 317)
Death is reminding us that humans are the ones who are selfish and self-absorbed. After all, it was humans that caused the war and the Holocaust.
