One, six, seven, go!

Today at William's pre-school, all the kids built kites by cutting a big circle out of a paper grocery bag and attaching streamers to one side, for a tail. William has been running back and forth for a couple minutes from our bedroom into the living room and back, trying to get some air out of this thing. Every time he gets to one end, he pauses and says "One, six, seven, go!" and takes off running again.
