Here's why:
* Private Expression: Unlike novels, essays, or even letters, journals and diaries are often written solely for the author's own eyes. This lack of an intended audience allows for unfiltered, raw thoughts and emotions to be expressed without concern for judgment or external pressures.
* Intimate Details: This freedom leads to the inclusion of intimate details, personal reflections, and even vulnerable moments that might not be shared with others. The writer doesn't need to consider how their words might be received or interpreted, allowing for a more authentic and personal voice.
* Unstructured Form: Journals and diaries often lack a strict structure or narrative arc. The writing can jump between topics, reflect on different moments in time, and be dictated by the writer's immediate thoughts and feelings. This lack of constraint further amplifies the personal nature of the writing.
Therefore, the lack of an intended audience is a defining characteristic that separates journals and diaries from other narratives, contributing to their deeply personal nature.
