The thief in her head keeps stealing the words

What she learns one day is gone by the next morning. Hwa-ja Park, at the literacy class in Beolgyo Library, gave the thief a name. A rascal living in her head who carries off every word she studies and stores away and leaves no trace. It is maddening, and still she picks up the pencil again. The will to sit back down after forgetting lasts longer than a good memory.
