He commented once that he liked his players to be “fun, but not funny”, and I think I finally know what he meant. People who reflexively use humor can make everyone laugh, but in most, perhaps all, cases, this is a psychological defense mechanism, which means that they are not fully present emotionally. They are hiding, and he didn’t want people who hid. This is inherently a separation from the core self, and the core self is where true emotional strength is found.
I recently heard second hand that among some people I knew years ago I was considered “fucking funny”. And I did used to joke a lot. I can be very witty at times, and very fast. But I am finding the more work I do, the less recourse to that I have. I am not as funny as I used to be, but I am also finding myself sometimes capable of staying in the room when dealing with other people, which I was not when I was deflecting with humor.
