Identifying the Author's Tone in Autumn Reflection

In the passage below, the author reflects on the changing seasons and their impact on human emotions:

"As autumn arrives and the leaves turn to vibrant shades of gold and crimson, there is a palpable shift in the atmosphere. The air becomes crisp, and a gentle breeze carries the scent of harvest. It reminds me of childhood afternoons spent under trees, and the bittersweet feeling that accompanies the escalation of shorter days and longer nights. Each fallen leaf seems to whisper stories of summer days gone by, merging joy with a tinge of melancholy. It is as if the world is simultaneously celebrating and mourning, capturing the essence of life’s fleeting moments."
