How does Dave Pelzer use imagery in The Lost Boy?

Imagery:

"I don't dare make a sound as I cry deep inside. I know I'm wrong. And as always, it's all my fault."

"Everything was too good to be true - the freedom, the new clothes, the toys. But the thing I cherished most was the warmth of Mother's hug. 'I'm so sorry about everything,' I sobbed. 'I really am. I didn't mean to tell.'"
