* Focus on personal feelings and experiences: The poem explores the speaker's desire for solitude and a sense of self-discovery, which are quintessential themes of lyric poetry.
* Lyrical language: Frost employs vivid imagery, figurative language (like metaphors and personification), and musicality in his language, creating a sense of rhythm and emotion.
* Subjective perspective: The poem presents the speaker's personal thoughts and feelings, rather than a narrative or objective account of events.
