Matching Tracksuits

The Boy comes out of the living room just as I’m headed that way. I jump in front of him playfully and block his way. As he shifts to the other side, I shift along with him, blocking his path. A fuss begins to arise. I lean down and whisper as if I’m keeping it a secret: “Push to this side like you’re going this way, then suddenly jump to the other side and run by.” He does so, then turns back smiling.

Why can’t I remember to turn every potential fuss into a teaching opportunity?
