The following lines from the beginning of the book describe what Katniss is thinking and seeing:
> "It’s the day of the Reaping. The day our yearly tribute to the Capitol is chosen. I’m already late. It’s against the law to be out past curfew, but there’s nothing left to steal at the Hob. No, that’s not true. There’s something. Prim."
These lines establish the stakes of the Hunger Games, the desperation of the people living in District 12, and Katniss's fierce love and protectiveness for her younger sister, Prim.
The specific words the lady says during the Reaping are:
> "Ladies first! Now, the youngest of the eligible girls. Please, step forward."
This line sets up the suspense of the Reaping and foreshadows the events that will follow.
