As we strolled hand in hand through the park on this crisp autumn day, she leaned over to me with a hint of melancholy in her voice and asked, 'Do you know?' Her gaze wandered to the delicate, yellowing leaves drifting lazily to the ground, and a tinge of sadness crept into her eyes. 'The ginkgo tree is very lonely,' she whispered, as if sharing a secret. I shook my head, and she continued, her words weaving a poignant tale of a bygone era. 'The ginkgo tree has looked like this for a few hundred million years, a relic of a time long past. Today, it stands alone, a sole survivor of its kind, its kin and contemporaries having long since vanished into the annals of history. Even the creatures that once called it home are scarce, a testament to the transience of life.' I couldn't help but think of humanity, our own fragile existence pawing at the earth, clinging precariously to the branch of time. And when we're gone, who will be left to inherit our places in the vast expanse of the universe? Perhaps, the lonely ginkgo tree will outlast us all, a sentinel of a time long since forgotten.
