Final answer:
The provided excerpts from a literary text use hair as a symbol to convey themes such as memory, change, and the essence of life, connecting physical attributes to deeper meanings within personal relationships.
Step-by-step explanation:
The passage provided appears to be from a work of literature, likely discussing themes of memory and sentimentality as evidenced by the man's contemplation of the lock of hair and the faded bouquet. The mention of hair acts as a symbol, perhaps connecting to the themes of time, change, or personal connections. The second excerpt further elaborates on this symbolism by comparing the color and growth of vine to a person's hair, suggesting a sense of life and natural beauty. The dialogue implies admiration and a deeper meaning attached to the physical attribute of hair, which often represents identity or personal history.
