Someone stuck at home all day finds that the thoughts they can't say aloud have nowhere to go. The speaker is full of "pent-up talk," and the title, "Internal dialogue," tells us the conversation is happening only in their head. With no one to listen, the speaker becomes both the talker and the audience.
The most striking image is the ear "like a state." An ear can seem a small thing, but here it feels like a whole territory, something with borders, with its own weather of sounds. The speaker's listening has become large and serious, almost governmental. Then comes the last line: with ink, the speaker "reckons" themselves "a world." Writing turns the private chatter into something solid.
The mood is a mix of isolation and quiet pride. There's loneliness in being home with only your own voice, but also a wry, playful confidence. Judging by the lines, the page is what rescues the speaker: ink makes a lonely day feel expansive.
