How does Ann Head use imagery in Mr. and Mrs. Bo Jo Jones?

Example of Imagery:

"We got to the chapel and Bo Jo eased the car into a parking space. Mother and Father's car was right in front of us, and in front of their car I saw to my horror Grandmother Greher's Lincoln. It had never occurred to me that she would be here. Even if Father and Mother had asked her, I couldn't imagine her coming, and the sight of her car turned me hot and cold with nerves. Up until then I'd drawn a veil where Grandmother Greher and Bo Jo and I were concerned. I mean in regards to what had happened. She was a person whose opinion of me mattered. Even though I wasn't even sure I loved her. Or even liked her." (64)
