Don't worry about what to say. If she says something you don't know how to answer (like the other comment she made), just shake your head and say that you're fine. Don't let her pull you into a discussion you don't need or want right now. If necessary, change the subject to what she did on her trip.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
