From Jennifer, Hecate, Macbeth, William McKinley, and me, Elizabeth by E.L. Konigsburg (a marvelous book which I somehow missed in childhood despite having loved others by Konigsburg):
So it happened that we got to meeting in the library every Saturday morning "at 10:00 a.m. o'clock of the morning," as Jennifer said. We'd check out our books. I usually took out one book besides renewing The Black Book of Witchcraft. Jennifer always took out seven books. I could tell that the librarian liked Jennifer even though Jennifer never said "hello" or "good-bye" or "please" or "thank you." Librarians love good readers, and Jennifer was that. In fact, Jennifer wasn't just a good reader, Jennifer was a serious reader.
Here's hoping that the librarians at my local branch feel the same way about me despite my penchant for requesting all manner of books from far flung branches and hogging a large section of the hold shelf on a regular basis...
