I am studying basic french and I encountered this question:
écrivez le phrase au passé composé. "Nous ne nous amusons pas au festival." Following the method I learned, I end up with "Nous ne nous sommes pas amusés au festival."
However, when I check my answer with my teacher's copy, the answer is "Nous ne sommes pas amusés au festival." The reflexive pronoun is not there.
Is the teacher's answer correct? If so, how does it work? I haven't learned of this and I cannot find an answer.
