the back of my heel

"Mommy," Keona said, "the back of my heel is sleepy but the rest of me isn't. So let's be quiet so I can rest for a while."

I responded with, "Okay baby," and immediately began counting silently to myself: "one-one-thousand, two-one-thou--"

"Mom, do you think we'll be able to visit Jupiter some day?"

I guess her heel had rested :-).
