history: When I was in college I was in a class with an older woman who was a returning student.  She heard me talking about a paper idea I had, then presented it as her own, stealing my work. I was in a college class once with an older woman.  She took a paper idea I had talked about and presented it as her own_comma_ stealing all the work I had done. That is despicable. Did you report her to the teacher?
current: I did.  There wasn't much she could do, but at least I could still do the same paper without having to redo a bunch of work.
next: She could drop her from the class and give her an F!
