My office is a cubicle farm, and my cubicle is on the edge of my work group's zone.  My neighbor who is not my coworker is "Joanne", and she's a very nice woman as far as I can tell.

Like many cubicle farms, the unspoken rule seems to be that you ignore anything you hear that isn't directed at you.  However, you still can hear...and I've heard Joanne talking to people on the phone (presumably family members, based on context) about a problem her college-aged son is going through.  Very specifically, he has tried to drop a semester for medical reasons, was denied, appealed, and then was denied again.  The medical drop is under particular circumstances which aren't important to the question.

Now, four years ago I got a retroactive medical drop from the same university in the same circumstances, and based on the details of what I can overhear, this person is going about the documentation and appeal process *all wrong*, and based on my experience I can give some advice on how to restructure it and some additional types of documentation to pursue that would drastically improve the chances of a future appeal being accepted.  This coworker seems nice, and I hate to have someone with a failed semester on their record just because they don't know how to document.  On the other hand, the circumstances are potentially very embarrassing to my coworker, and I don't want to make her uncomfortable or upset.

WIBTA for trying to pass her advice?  Is there a way I can pass her advice that would minimize the level of assholery?
