How does Carolyn Parkhurst use imagery in Lost and Found?

Imagery:

“For so long, it was just my secret. It burned inside me, and I felt like I was carrying something important, something that made me who I was and made me different from everybody else. I took it with me everywhere, and there was never a moment when I wasn't aware of it. It was like I was totally awake, like I could feel every nerve ending in my body. Sometimes my skin would almost hurt from the force of it, that's how strong it was. Like my whole body was buzzing or something. I felt almost, I don't know, noble, like a medieval knight or something, carrying this secret love around with me.”

“It was September, and there was a crackly feeling to the air. I was saying something that was making her laugh, and I couldn't stop looking at her. It was a little bit chilly, and her cheeks were pink, and her dark hair was flowing around her face. All I wanted for the rest of my life was to keep making her laugh like that. Sometimes our arms brushed against each other as we walked, and it was like I could feel the touch for minutes after it happened.”
