On page 22, Wiesel calls his former neighbors ''our friends of yesterday.'' What does this suggest about Wiesel's attitude

In context, we can infer that Elie, as well as the others leaving for the station were disillussioned and disheartened. Wiesel knew what would happen when they left, as he had seen it happen for himself. His "friends of yesterday" were those left behind. The fact that they'd take whatever they could.... that they'd loot what was left behind, leaves Elie feeling betrayed.
