What mainly does the first paragraph reveal about Phoebe?
A few days after Phoebe and I had seen Mr. Birkway and Mrs. Cadaver whacking away at the rhododendron, I walked home with Phoebe after school. She was as crotchety and sullen as a three-legged mule, and I was not quite sure why. She had been asking me why I had not said anything to my father about Mrs. Cadaver and Mr. Birkway, and I told her that I was waiting for the right time.
