I see children as kites. You spend years trying to get them off the ground. You run with them until you are both breathless... They crash... You patch, comfort, and assure them that someday they will fly.
Finally, they are airborne. They need more string and you keep letting it out, but with each twist of the ball of twine, there is a sadness that goes with joy.
The kite becomes more distant, and you know that it won't be long before that beautiful creation will snap the lifeline that binds you together and it will soar as it was meant to soar - free and alone.
