Arendt talks about the public

“To live together in the world means essentially that a world of things is between those who have it in common, as a table is located between those who sit around it; the world, like every in-between, relates and separates men at the same time.“

The last quote is from Hannah Arendt, The Human Condition, Chapter 2 (“The Public and the Private Realm”), specifically the section titled “The Public Realm: The Common.”
