In J.D. Robb's book "Visions in Death," there’s a playful exchange between characters about the nature of advice. One character offers a tip that suggests approaching life with a positive attitude, while another humorously counters, warning that a smile alone won't prevent misfortune, illustrated by the metaphor of getting wet in the rain. This dialogue captures both optimism and realism in dealing with life's challenges.

The interaction highlights a common theme in relationships, where differing perspectives often lead to witty banter. It emphasizes the importance of a light-hearted attitude, even when facing difficulties, while also acknowledging that positivity is not a foolproof shield against adversity.
