Last Wednesday, I was working in the main library and had HRH connected to my chair with her bone nearby. I always have a big crowd of kids in the library in the morning. HRH was playing with the bone, which involved a great deal of rolling around on the floor, flipping over and then in deep despair, howling at the temerity of the bone not falling apart as she wished. When she did this, Carter, who was sitting two tables over leaped to his feet and cried out,
"I've got this!" and ran over to HRH carrying only his chemistry book. Then he proceeded to calm down HRH for the next 20 minutes until classes started at 8 am, all the while continuing to study his chemistry (our students are compassionate and focussed! 8-).
Here's a shot of the two of them. HRH actually did calm down. She doesn't do that for most people. Carter has the touch.
