I know a lot of people are talking about the disingenuous nature of networking and your response is totally valid. Business runs on relationships.
But those relationships don’t form if it wasn’t for business. Sometimes beneficial for all parties, sometimes not. Hopefully people understand that this should not be the extent of all your relationships nor should you confuse work friends with friends outside of work.
In a world where the dominant culture emphasizes our ability to do work and create fiscal value it can seem like people have excised an important part of themselves.
