Sally Rooney's novel as chamber play

Sally Rooney's novel Conversations with Friends opens w/ a cast of 4 - and in fact feels somewhat like a chamber play, at least at the outset: the narrator, an experimental poet and a committed socialist, late 20s, living alone in Ireland (not in Dublin); her best friend, a beautiful and talented actress/performer - and the 2 of them do performance art, based on poems that the narrator writers. At the outset they meet an author/photographer, impressed by their performances, who wants to do a photo-essay about their work, and the photographer's husband, a handsome man currently performing in Cat on a Hot Tin Roof at the Royal (Irish) theater. Tensions build among the 4 as there the performer is obviously attracted the husband who in turn, surprisingly, is drawn to the eccentric an less attractive narrator; the photographer seems to coolly observe these developing relationships from afar - perhaps part of her work. I was interested in the narrator's description of her poetry, which, she says, she never writes down much less publishes, so they live only in the act of performance. She expresses some sorrow for poets who do write/publish their work - they have to live w/ these published pieces forever, whereas she gets sick of her poems after about 6 months and is pleased to let them vanish.
