Holden could be in various settings, like a coffee shop or a library, where he feels comfortable sharing his thoughts. It depends on the specific context of the story. Sometimes, he might even be walking alone on the street while opening up.
Holden tells his story from different locations throughout the narrative. It could be in a dormitory, on a bench in a schoolyard, or any place where he finds himself with the urge to express his experiences and feelings.
He is usually in a secluded or introspective place, such as his room or a quiet corner of a park.
