In Margaret Atwood's collection "Selected Poems: 1965-1975," she explores themes of identity, memory, and the complexities of self-awareness. The quote, "I began to forget myself in the middle of sentences," reflects a profound introspection and the struggle with one's sense of identity. It suggests moments where thoughts and words may become disconnected, leading to a loss of self amidst articulation.

This realization resonates with the experience of how external influences and internal conflicts can blur one's understanding of who they are. Atwood's poetry captures this phenomenon, illustrating the delicate balance between expressing oneself and the fear of losing one’s essence in the process of communication.
