In "Don Quixote," the character expresses the idea that using proverbs can enhance communication when used appropriately. However, he cautions against the excessive and random use of proverbs, which can lead to conversations that lack depth and become tedious or common. This insight highlights the importance of thoughtful dialogue over mindless repetition.

The observation serves as a critique of overly simplistic or formulaic communication. It suggests that while proverbs have their place in conversation, relying on them too heavily can detract from meaningful interactions, making discussions feel less engaging and more superficial.
