Last year I was teaching a class for a group of second and third graders; 7, 8, and 9 year olds. One afternoon as I sat on my mat an inquisitive little yogini sat next to me and took notice of my wrist. “What is that?!” She asked, clearly concerned about the protruding bulb sticking out at the end of my forearm. “It’s my bone.” I replied. Her concern turned to curiosity as I tried as best I could to explain about the ulna’s functions in the body.  When I said, “Look you have one too!” curiosity turned into shock at never having noticed this part of her own body before. She was however, clearly comforted by the fact that I have one too and it’s totally normal.
