This is a general observation rather than a hard rule.
I’ve noticed that in some social or work situations, certain men seem uncomfortable when there’s strong male company around - particularly confident, competent or assertive men, and it can come out as withdrawal, competitiveness or subtle hostility. I’m not suggesting this applies to all men (or only men) but I wondered whether others have noticed this dynamic too, or whether I’m over-interpreting normal social behaviour.
AIBU to think this is a thing?
