Joy. Joy at being included. Joy of accomplishment. Joy of connection with everyone. And...
There is such joy in telling someone who is differentially abled "I will help you achieve that goal" instead of the usual "You can't do that".
Somewhere there is a newspaper photograph of my brother rappelling down a rock face a few decades ago. The enormous smile and complete joy at his accomplishment leaped off the page. It was beautiful. I miss him, and his giggly sense of humor.
