In "The Lost Art of Gratitude," Isabel reflects on the nature of kindness and virtue. She observes that those who care for animals tend to exhibit genuine kindness, often practicing it quietly without seeking recognition. This contrasts with those who publicly display their good deeds, suggesting a depth to kindness that lies beyond mere outward appearances.

Isabel believes that true virtues flourish in discretion and are best appreciated by those who directly benefit from them. She posits that the most meaningful acts of kindness are those done in silence, known only to the doer and the recipient, highlighting a profound understanding of altruism devoid of public validation.
