The quote from "The Last Unicorn" by Peter S. Beagle captures the transient nature of enchantment. The speaker suggests that any magic affecting them will dissipate the moment they gain their freedom. This implies a sense of liberation from superficial illusions that can easily disappear.

In contrast, the enchantment stemming from another's mistakes is portrayed as a permanent burden. The speaker indicates that they will always be seen through the lens of those errors, signifying a lasting impact on their identity and perception. This highlights the theme of how the actions and perceptions of others can leave an enduring mark on one's life.
