War and Peace Volume 2, Part 1, Chapter 12 Summary

The young people are all psyched to go out and dance at the ball. It’s fun on every level – there’s the dancing itself, obviously, and the flirting, and some people have even met their spouses there.
It’s beautiful; everything and everyone is sparking. Natasha especially – she is the best dancer there.
Denisov can’t stop talking about Natasha. He sits out the first dance and watches her dance with the dance instructor.
But then Natasha comes to ask him to dance, and after pretending like he doesn’t want to, Denisov busts such a move on the floor that every girl immediately wants to dance with him.
However, he spends the whole rest of the evening by Natasha's side.
