So it goes for parents and daughters too.
That pic is only half right. I get the message it is trying to convey; but it isn't right in that the father becomes less or is diminished while the son becomes more. They both become more complete and better people. With my daughter the more I gave - the more she threw away. Pieces of me went with her when she left.
If you ever find yourself in the same boat my advice is this: Patch yourself up first. It's the prime directive for even professional firefighters and rescue workers. Ya can't save or rescue others if you are a victim of the same circumstances.
