Salad days意思
"Salad days" is an English idiom that refers to a person's youthful, inexperienced, and often carefree days. The phrase is believed to originate from Shakespeare's play "Antony and Cleopatra," where Cleopatra refers to her younger, more naive days as "green in judgment, cold in blood, / To say as I said then."
The term "salad days" was used to describe the tender and green state of lettuce, which is at its best for eating when it is young and fresh. Shakespeare used the phrase metaphorically to suggest that Cleopatra's youthful innocence and lack of experience were akin to the freshness and tenderness of salad greens.
Today, the phrase is used more broadly to describe the early, inexperienced period of anyone's life, especially if it is associated with a sense of nostalgia or a longing for a simpler time. It can also be used to refer to a period of time when someone or something was in its prime or at its freshest and most vibrant.
