Colonel Brandon: Your sister seems very happy.
Elinor Dashwood: Yes. Marianne does not approve of hiding her emotions. In fact, her romantic prejudices have the unfortunate tendency to set propriety at naught.
Colonel Brandon: She is wholly unspoilt.
Elinor Dashwood: Rather too unspoilt, in my view. The sooner she becomes acquainted with the ways of the world, the better.
Colonel Brandon: I knew a lady very like your sister - the same impulsive sweetness of temper - who was forced into, as you put it, a better acquaintance with the world. The result was only ruination and despair. Do not desire it, Miss Dashwood.
