So very well observed. Goes the same for (fine) artists who are basically in a life-long therapy session! I imagine you do more smiling than laughing. I, however, am fast entering the dippy stage of laughing my socks off most of the time. It's mad out in the world, I can't help it. Literally...I don't think I can help much!
I'm learning how to loosen up and laugh a bit more myself. I think it might be necessary if one wants to survive! :D
