In Kelley Armstrong's book "Omens," the quote emphasizes the differences between a casual friend and a true friend. It suggests that a real friend is someone who exceeds ordinary expectations and is willing to go to extreme lengths, even in dire or unusual situations. The idea is that the depth of a friendship can be measured by how much support and loyalty one offers during challenging times.
The imagery of helping to move a body serves as a hyperbolic example of the ultimate trust and commitment present in genuine friendships. It reflects the notion that true friends stand by you not only during trivial matters but also when facing significant life challenges. This concept invites readers to reflect on their own relationships and recognize the value of having someone trustworthy and dependable in their lives.
