Read the following excerpt from a memoir:
"In the quiet moments of the early morning, as the world outside my window awakened, I felt an overwhelming sense of peace. The soft chirping of birds harmonized with the gentle rustle of leaves, creating a symphony of nature that enveloped me. It was in these fleeting hours that I found solace, a refuge from the chaos of daily life. Each sunrise brought a new beginning, reminding me that hope was ever present, waiting just beyond the horizon."
