Joy is Measurable
I was waiting for my husband to finish the 2nd leg of the Iron Man. It's a long wait, let me tell you that. But while I was sitting, camera ready to capture his moment, I captured this one too. She spent a good deal of time waiting on her daddy, and occupied herself the way only little kids do. She scooped up a handful of brush and threw it into the air, always pleased beyond belief when it magically fell back to earth.
Joy is measurable. We just outgrow the ability to find the tools with which to measure it with.
