The quote "what a tangled web we weave when first we practice to deceive," found in L.M. Montgomery's "Anne of Green Gables," reflects the complexities and consequences of dishonesty. It suggests that deception often leads to complications and unforeseen issues, making situations more difficult than they initially appeared. The sentiment indicates that lying can create a complicated network of untruths, which can entrap both the deceiver and the deceived.

This theme resonates throughout the narrative as characters navigate relationships and the impact of their choices. Anne Shirley's imaginative nature sometimes leads her into trouble, emphasizing that honesty and authenticity are crucial for genuine connections. By illustrating the pitfalls of deception, Montgomery underscores the value of truthfulness and the clearer path it offers in life's journey.
