While reading the works of Isaac Bashevis Singer over the past couple months, I've gotten the impression that Singer will often - especially in short stories - leave you with a sense that not everything has been resolved, and that crucial developments within the story never received closure.
For instance, the ending of "Pigeons" leaves you with a sense of something missing; there's no closure with the killers of the professor.
In "The Cafeteria", a major part of the story, Hitler being spotted in a restaurant, is never explained or resolved.
In "The Mentor", the story ends with a statement of despair and nothing is resolved.
Aside from these examples, somebody I spoke to mentioned that a lack of closure in Singer stories had come up while studying literature at Bar-Ilan, although they don't recall enough to comment on it.
Is a lack of closure a consistent theme throughout Singer's works? What could be behind this, if so?
