In "The Blind Assassin," Margaret Atwood explores the complexities of communication and interaction between our internal thoughts and the external reality. The passage raises questions about the boundaries between these two realms, suggesting that we navigate through them unconsciously every day. This process is likened to passing through a gateway, highlighting the fluidity of our experiences.

Atwood emphasizes the significance of language in this exchange, describing grammar as a form of currency that allows us to make sense of our world. By using commonly accepted meanings, we maintain our sanity and connect with others, illustrating how language shapes our perceptions and interactions with the outside world.
