How much is *too much* help?

I’m all about collaborating with other peers and helping each other out. Sharing resources and peer editing and things of that nature.

But I have a friend in class (we’re both grad students) who’s constantly asking to see my work. I feel obligated to share with her because we’re friends outside of school, but I also feel like she’s taking advantage of the help I’ve offered throughout the semester.

When she just asked for clarification on things, I didn’t mind at all. But I’m putting time and effort into this work she’s asking to see and it’s going to be pretty upsetting if she just copies me.

How would you all draw the line?
