I've written about this before, recently even. But it's worth repeating.
There's a different C that most people don't see, and this is the C who comes out when it's quiet. I mean, really quiet. And not just when it's quiet, but when we're quiet.
Instead of unresponsiveness, C answers. Instead of silly talk, he is frank and funny, and sometimes poetic. For example, just after I took the photo above I asked him what he was doing (he was so intent and still, very unusual for him), and he said, "I'm listening to the quiet."
Quiet. It's hard to come by. But it's worth it when you can find it.
