Melinda doesn't know study hall is in the library today, because yesterday Hairwoman took her out of study hall to do a make-up assignment in her classroom.
When Melinda gets to the library, study hall is over. She tries to tell the librarian what happened, but she can't find the words.
The librarian tells her not to worry. She has a pad of late passes, and she gives one to Melinda.
Melinda feels better and checks out some books that she might even read.
At lunchtime, Mr. Neck is following Melinda around trying to get some homework from her. She escapes him by going into "the Senior's Wing" (11.4). She's never been here before.
Mr. Neck is hot on her trail, but she ducks into what she thinks is a classroom. Luckily, it isn't a classroom, but a janitor's closet, one which doesn't seem to be in use anymore. The closet has shelves, a chair, a desk, and a mirror.
This abandoned, out-of-the-way closet is just what Melinda needs.
She snags a pad of Hairwoman's late passes and her mood improves.
