The quote from Diana Gabaldon's "Voyager" emphasizes the universal nature of deceit, suggesting that everyone, regardless of their circumstances, can lie if the situation warrants it. It points out that while lies may come easily to some, for those who are constantly scrutinized, like the speaker who describes themselves as living in "glass faces," premeditation becomes necessary. This highlights the complexity of honesty in a world where motives and consequences can drive individuals to distortion.

The mention of "glass faces" symbolizes vulnerability and the constant observation from others, suggesting that those who are more visible must navigate their truth carefully. The speaker acknowledges their own capacity for deception, underlining the idea that integrity is often tested by external pressures. Ultimately, the quote reflects on the human experience of navigating honesty amidst the complexities of societal judgment and personal integrity.
