Hello,Laura. Will please look at page 25.

Your editing:
Five minutes later, they met at a park near the school. The gardens were clothed in bright autumn colors, and the lawn and paths rustled with the fallen leaves. The sun was shining and the air was fresh. They as a whole formed a perfect backdrop for a romantic picture, toward which they had yet to move far enough in their relationship. Or, perhaps, the case should never arise. Who knew?

My revision of the last portion: They as a whole formed a perfect backdrop for a romantic picture, but he didnt suggest taking a picture of themselves. He knew they had yet to build closer relationship for it. Or, perhaps, the case should never arise. Who knew?

Will you check to see if my revision works?
I'm sorry to trouble you. Thanks again.
