Quote 10
"I don't want to talk about it," Miss Honey said. "It's too horrible. But in the end I became so frightened of her I used to start shaking when she came into the room. You must understand I was never a strong character like you. I was always shy and retiring." (17.43)
This is one scene in the book in which the Trunchbull's violent abuse takes a turn from the hilarious to the horrible. Her treatment of Miss Honey is in no way funny. It's tragic, sad, and has left Miss Honey severely damaged, maybe for life.
Quote 11
"After my father died, when I was five and a half, she used to make me bathe myself all alone. And if she came up and thought I hadn't washed properly she would push my head under the water and hold it there. But don't get me started on what she used to do. That won't help us at all." (18.4)
We get a lot of hints about how dreadful the Trunchbull's abuse of Miss Honey was, like the fact that she would push the teacher's head under the water and hold it there, but we don't get many details beyond that. Nevertheless, when you stop to think about it, you realize just how incredibly violent the Trunchbull was (and still is!). Just imagine how terrible the other things she did must have been, if Miss Honey doesn't even want to talk about them at all.
Quote 12
"[…] I hated her [my aunt] right from the start. I missed my mother terribly. And the aunt was not a kind person. My father didn't know that because he was hardly ever around but when he did put in an appearance, the aunt behaved differently." (17.25)
Miss Honey could've told her dad about the aunt, but chances are he wouldn't have believed her—and then the aunt would probably have gotten even worse as a result. Sometimes it's tough being a kiddo, and not having much of a voice.
