Children seem to be on the move constantly. While I’m saying that in reference to their physical state of being I think it also applies to them in a metaphysical sense as well. Perhaps they have to keep moving in order to give some kind of release to all that change that builds up inside them like a coiled spring.
The fact is that if you look away for just a moment they are gone and somebody else is in their place, somebody older and wiser and you can never change them back. So for now just don’t take your eyes off. And when they run away, run right along with them.
