That's very true. I wasn't he one calling it a curfew and i agree, it is not the best term for these kinds of things.
Sorry for the misinterpretation. it just helped me see something in a way i felt was applicable to how i was responding to the situation, but i see what you mean in its application towards how it might be making her feel as well.
I hope that is not the case, and if it is then she has put that feeling upon herself in a way by refering to it as a curfew.
