I ask the bookstore lady if the books are hiding somewhere or if they just don't have them or what. She says they're out, and she didn't know the books were required, she thought they were just recommended. She calls the book supplier on the phone, and orders me the Japanese-English dictionary for overnight delivery. But they're out of the English-Japanese ones. Indefinitely, they say.
With a bit of exasperation, I decided to not worry about it then, and bought You Are Being Lied To instead. And a little blue stapler.
That'll be enough for now, I guess.
