While I am self employed, my clients can end up like my boss. In this case, one of my clients is the best "boss" I have ever had. We discuss everything from ethics to npm to development to board games. And we still get the job done.

He challenges me constantly to improve, and then we laugh over how we disagree with concepts, frameworks, etc. And we still get the job done.

It's fantastic to have a client who understands that you should be paid for your time, that lets you get what they hired you to do done without micro managing you (you trust me to actually do what you hired me to do? *gasp, shock*), and still enjoys the small talk. Though some of our ethics and society discussions can be rather large discussions.
