I've recently received a cold message from a colleague's spouse, writing that they've heard my "name from <my colleague's name> over the meetings", asking for mentorship to help them (the spouse) finding a job in the same industry as the one we work in, and they also asked me to set a time and date for a session since I am "the one with a real job and responsibilities."
I mentor young graduates outside of my working time fairly regularly, and in general, I like helping others when I can, but in this particular situation, it seems more like a domestic problem, especially since I didn't get any heads-up from my colleague to expect their spouse messaging me, let alone asking for consent.
The last thing I want is to walk on eggshells, and unintentionally get in their relationship internal workings. How would you handle such situation?
