This morning I found this quote in "Northange Abbey", referring to Mr. Tilney's sister, whom Catherine has just met at a ball:

"Her manners showed good sense and good breeding; they were neither shy nor affectedly open; and she seemed capable of being young, attractive, and at a ball without wanting to fix the attention of every man near her, and without exaggerated feelings of ecstatic delight or inconceivable vexation on every little trifling occurrence."

She sounds like a Buddhist!
