The quote from Martina Cole's book "Get Even" emphasizes the value of good manners and how little effort it takes to practice them. It suggests that being polite and respectful towards others is a simple yet significant action that can leave a lasting impression. Manners, often overlooked or undervalued, can significantly enhance interpersonal interactions and contribute to positive relationships.

The phrase "cost fuck-all" highlights that good manners do not require any financial investment; rather, they stem from an attitude of respect and consideration. Cole’s message underscores the idea that kindness and courtesy can make a substantial difference in how we engage with one another. By valuing and practicing good manners, we foster a more pleasant and harmonious environment in our daily lives.
