In Alice Munro's "Lives of Girls and Women," the quote "One stroke of lightning does not have to lead anywhere, but to the next stroke of lightning" suggests that experiences in life may not always progress in a linear fashion. Instead, they can be spontaneous and unpredictable, much like lightning. Each event or moment may stand alone, yet they also have the potential to spark new experiences, initiating a chain reaction of insights and revelations.
This metaphor highlights the nature of personal growth and the interconnectedness of life events. It encourages embracing the unexpected turns that life takes, recognizing that each moment can lead to another, shaping one's journey in unforeseen ways. In this sense, Munro invites readers to appreciate the beauty of individual experiences without needing to find a clear purpose or destination in every moment.
