Read the excerpt from "I'm Not Thirteen Yet" by Amy Bernstein.

Three weeks later, I reluctantly boarded the bus with all the other Shenandoah-bound kids. Just before I stepped on, Margaret's mother and mine asked to take a picture of the two of us. I wanted to throw up, but smiled graciously as the camera flashed and our moms grinned.

Why does Jamie feel like she is about to get sick?

because she does not like summer camp
because she dislikes having her picture taken
because she and Margaret are not friends
because the flash from the cameras hurts her eyes
