Flight behavior refers to the actions and reactions of individuals or groups in response to perceived threats or changes in their environment, often resulting in a physical or metaphorical departure from a situation. In the context of 21st-century British literature, this concept is increasingly relevant as it reflects the impact of technology and globalization, shaping how characters respond to societal pressures, personal crises, and cultural transformations. The term encompasses themes of escape, adaptation, and the search for identity amidst rapid change.
