She returned to her 12th birthday bcuz she thinks it was unimportant. While she was reliving this she realized that all humans are blind. She realized that she took life for granted and did not appreciate the little things. She did not appreciate what she had until she had lost it. In the beginning the other dead people had warned her not to return to the land of the living but she still did it. When she returned she told them "I should have listened to you. That's all human beings are. Just blind people. Thornton wilder is trying to get the readers to appreciate the small things because later on they become things you regret that you did not appreciate.
hope this helps :)
If the question is in what sentence do you see a predicate adjective, then the correct answer is in the first one - Not all deserts are sweltering, where the word <em>sweltering </em>is a predicate adjective.
A predicate adjective is an adjective that can be found following a verb.
Gregor can't handle the furniture moving. He crawls out from behind the couch and globs onto the first thing he sees. It is a picture on the wall of a woman in furs. I think Gregor doesn't want to lose the possibility that he might become human again. The furniture reminds him of this.
