That's funny, it's my and my husbands 30th in January. We made a deal with our kids as they got older. They were either in school or they were trying their best to have a job and work. We required that 1/3 of their income was given to us for board, 1/3 went to the bank, and 1/3 was theirs to play with.
Some people may think that that was a little harsh but, when they were ready to fly away, they had learned to pay their bills and had money to rent a house in the bank. We were never rich parents, barely made it sometimes, we felt it was important that they learn to live within their means and just how fast money can go.
They are all doing well now and I'm proud of them. They all know they live here any time they need to, but, the deal still stands.
