Awkward Turtle

Last week, I returned a corrected assignment to a student. She had translated some Japanese sentences into English. A Japanese teacher of English (JTE) was walking with us. I complimented the student on her work, but I pointed out some sentences that I didn't understand. Then, I was in the middle of telling her that her grammar was mostly good, when the English teacher told me that she had in fact written most of the sentences. I didn't know what to say.

Awkward turtle.

And why had the teacher done most of the work? >_<
