5. Summary of the poem "Road Not Taken" by Robert Frost

Imagine standing at a fork (a point where a road splits into two different paths) in a quiet, golden forest. Two roads lie ahead, but you can only choose one. The poet, Robert Frost, picks the less-traveled path, symbolizing the choices we make in life.

This poem beautifully reflects how our decisions shape our journey and future. The "road" is a metaphor for life’s opportunities, and the poet’s choice represents individuality and courage. In the end, he looks back with a sigh, realizing that this one decision made all the difference in his life.

Moral: Life is all about making choices, and the path we choose defines who we are.
