In "Watermelon," Marian Keyes humorously highlights how physical attraction and romantic interest often overlook personality traits like kindness. She suggests that if kindness were a primary factor in attraction, then remarkable individuals like Mother Teresa would be inundated with suitors. This blunt observation critiques societal norms surrounding dating, indicating that many prioritize superficial qualities over genuine character.

Keyes' quote reflects a common dilemma in relationships, where qualities like compassion might not hold the same allure as looks or charisma. The statement serves as both amusement and a reality check about the nature of attraction, urging readers to reconsider their perceptions of romance and connection. Ultimately, it emphasizes that kindness, while admirable, isn't typically viewed as an attractive trait in the pursuit of love.
