They [missionaries] were kind and praised me when I responded to the simple commands they issued in Japanese: sit, eat, sleep. Had they asked, I would also have responded to "close mouth" and "open legs". At the camps where the Japanese called us Jungun Ianfu, military comfort women, we were taught only whatever was necessary to service the soldiers. Other than that, we were not expected to understand and were forbidden to speak, any language at all.
