I love this quote:

Children Are Like Kites

By Erma bombeck

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

Only then do you know that you have done your job.
