motion

Even standing stock still this girl is in motion.

We finally solved the single-ball fetch riddle - the proper series of commands to get her to relinquish the ball is "drop it," "back back back," and "stay." At that point, it's OK for me to pick up the ball and throw it. ("Drop it" alone followed by an attempt to grab the ball ends in a game I can't win, called "toooo slowwww," but she follows the sequenced steps every time.)

We're also working on "find it," which she really seems to enjoy.
