So I meet with my mentor at work from time to time. The intention is that he provides career guidance, advice, etc. Which he does, sometimes, and sometimes it's marginally helpful. But during our meetings, what he mostly wants to talk about is how much I eat (he thinks I don't eat enough hence am too thin). And how old are my kids, etc, etc.
Now of course, it's fine to chat with colleagues about non-work stuff, including kids, and that's fine. But my suspicion about this man is that he doesn't really think I am very serious about my career, mainly BECAUSE I have kids. This matters, because he does have some influence over my career.
It is true that my career is in the doldrums, and that doe relate, at least partly, to the fact that I can't and won't work the very long hours that many of my peers do (I'm an academic). But on the other hand I don't want to be entirely written off. This is slightly complicated by the fact that I'm pregnant and god only knows what he's going to want to talk about when I tell him that.
So do I just humour him, and find another informal mentor? Do I tell him that it's inappropriate to talk about my weight, which he would probably take as a sense of humour failure on my part? Do I ask for a new formal mentor? That would be awkward, as he's well liked within the department as far as I know, and surely I'd have to explain why? WWYD?
