I've nothing else to bring, you know,
bring, you know
Dickinson's conversational 'you know' creates intimacy—she's apologizing for repeating herself, like talking to a close friend who's heard this before.
night keeps fetching
Active verb choice: the night 'fetches' stars like a servant bringing gifts. Stars aren't just appearing—they're being deliberately delivered.
Maybe we shouldn't mind
Double negative logic: we shouldn't mind them (dismiss them as ordinary) unless they stopped coming—then we'd realize their necessity.
To find our way home
Stars as navigation tools. Without these 'familiar' repeated things, we'd be literally lost—not metaphorically, but practically unable to orient ourselves.
