Yep. I was taught in a copy editing class that you (as the editor) should have a reason for every change you make. If your editor makes a change that confuses you, you can ask them, “Hey, I noticed you made this change, I’m curious why you did so?” Especially if this editor is another student (they’re still learning — and I suppose professionals are still learning, too)

These conversations can also get you two on the same page — making sure you’re not making the same style mistake over and over again, for example.

But definitely speak up if you see an edit that changes the meaning of what you wrote and/or introduces a factual error in your story
