"It is happy for you that you possess the talent of flattering with delicacy. May I ask whether these pleasing attentions proceed from the impulse of the moment, or are they the result of previous study?"

This quote by Jane Austen is a subtle method of asking if the individual she is speaking to is naturally talented at flattery or if they have actually studied and practiced it. She is implying that the person has a skill for flattery, but she is also curious to understand if it is something that comes naturally or if it is something that has been found out. It is a compliment, but likewise a concern. She is recommending that the person has a special skill, but she is also questioning if it is something that has been developed with time. It is a creative way of asking if the individual has a natural talent or if they have actually worked hard to perfect it.
