A further example, when she texted one of the mentors, she got back:
I am not trying to be too invasive in the reasons, but would like to know the reasons of the early split.
To which she states:
This mentor said he wasn’t trying to be invasive, but he was.
Then she says that how they really should have responded was (edit: this is another actual response):
Thanks for letting me know, [I’m] sure you had good reasons and I’m glad to hear that you’ll continue on with [Project].
OK, I get why you'd prefer the second response, but considering what happened, it's not rude for them to ask what's up, and they even padded that question so as to not be demanding. It's possible that's an unusual situation for them. I kind of get the feeling that neither person is really fun to work with, but that's based on what's in this blog post.
I don't mean to be a jerk or victim blame or anything like that.
