Dear Child of Mine, We both know that you won't save anything so I am going to insist you pay me for bed and board. Then, when you suddenly decide you want to move out and come to me and moan that you've no money for a deposit/rent etc, I shall be able to help you out. I am saving for your future as you won't do it. Don't pretend you will. I love you but let's be honest. Give me money for bed and board or go paddle your own canoe. Ah, but @blazer knows his own kids so his way worked for his family. Horses for courses.
