If a man was a carpenter, his son was likely to be the same. That's because the shop was at home and the boy worked with his father. The son watched carefully as Dad cut the wood, planed and smoothed it, then fastened it together to build a table or a bench. It was apprenticeship by example. Most young people don't learn their trades like that anymore.
Vocations are far too complex and the training way too demanding.
One aspect of life, however, is the same as it was years ago. Children not only learned how to do things from Dad and Mom, they also learned about life. They saw their parents' values and ethics in action every day in their homes. And young people not only need it, they want it. Children may close their ears to advice, but their eyes are always open to example.
