Here's why:
* Nostalgia: The poem is filled with memories of the narrator's childhood, specifically the time spent with his grandmother. The vivid descriptions of the tree, the climbing experience, and the grandmother's character create a sense of longing for a simpler, happier time.
* Admiration: The poem highlights the grandmother's strength, courage, and adventurous spirit. She is portrayed as a role model, someone who inspires the narrator to be bold and curious. The lines "She climbed as easily as a bird/Up to the highest branches" and "Her eyes were as bright as the leaves" depict her with awe and respect.
The tone is also gentle and humorous, reflecting the warmth and playful nature of the relationship between the narrator and his grandmother. The poem is ultimately a celebration of their shared love for nature and their ability to find joy in simple things.
