A couple years ago I wrote a post about playing the Wii with Henry, even as his avatar bore the signs of his chemotherapy.
He never elected to change it to one with hair, though he did add a hat and sunglasses at one point.
There are certain games where the Wii populates "extras" with various saved avatars. It's oddly comforting to see Henry unexpectedly driving in the car next to you. I like it.
