In Alice Munro's "Too Much Happiness," the protagonist experiences a moment of realization regarding the complexity of nature. He observes a bush that he has overlooked in the past, now seeing its intricate and intertwined branches. This newfound awareness highlights the interconnectedness of the trees, which work together to create a dense and secretive environment. It signifies a change occurring subtly, almost unnoticed.

This moment reflects a deeper understanding of the world, where individual elements interact to form a greater whole. The bush symbolizes transformation and the hidden depths of life that often go unrecognized. The protagonist's attention leads to an appreciation of the beauty and complexity that exists in what was previously taken for granted.
