My/My/My by Charles Bernstein is a comment on fiction writing and the authenticity of the voice of the protagonist. By using 'my' followed by a thing we learn nothing about the author or character in question, it's simply a list of ownership that doesn't give us further description or understanding.
For me the idea of listing these objects and items with this continuous connection to being owned by someone creates this unknown, the first person narrative simply just connects these together, no more no less. The audience doesn't connect to the character in a way they might while reading fiction books, the structure makes it readable but not connecting as such.
