How does Leslie Connor use imagery in Waiting for Normal?

Example of Imagery:

"I didn't care that it wasn't likely to happen, or that I was just a pebble in a big sea that would decide what to do with me."

“Normal …is when you know what’s gonna happen next. Not exactly what, because probably nobody gets that. But normal is being able to count on certain things. Good things. And it’s having everyone together—just because they belong that way.” I realized I was making a circle with my hands as if I were holding on to a tiny world.
