The quote suggests that deceptive thoughts can linger in our subconscious, like bats hidden in dimly lit spaces. These lies are not always visible but are ready to emerge when we face uncertainty or negativity. They can take advantage of moments of weakness, revealing how easily our minds can be influenced by deceitful ideas.

In Alice Munro's "The Love of a Good Woman," the imagery of bats emphasizes the hidden nature of these falsehoods. Such lies can infiltrate our thoughts subtly, awaiting the right moment to cause distress or confusion. This metaphor highlights the importance of confronting our inner darkness rather than letting those lurking deceptions overpower our judgment.
