In "the hollow men", what do the "hollow men" do together

"Obviously, when Eliot uses words such as hollow, dried, and broken to describe the hollow men, he doesn't mean it literally - it is always a metaphor when poets use words in order to convey a message. So here, when he uses those words, he means that the lives of hollow men are empty - void of spirituality or meaning.

He doesn't refer to them gathering supplies, being damaged by the wind, or not having money - he is referring to their empty lives in general."
