Even if it wasn’t so much “manipulative”.
If you care you’re a good person. If you pretend to care in order to network then you’re being mildly manipulative.
Bingo. I think that’s the key to it - if you do it with the intent of getting something from someone, people will work that out pretty quickly and resent it. It comes over as being…greasy.
If it’s done from the perspective of having genuine interest, care and empathy it makes it easier to work as a group.
