A DMK Production
You helped your sons, ten year old Aaron and twelve year old Adam, build a tree house. It was a good experience for all of you. The boys learned a lot about tools and building and carpentry. You do allow the boys to use power tools but require that you be present to supervise.
The boys decide that they want some furniture for the tree house and decide to build some benches. The boys decide they know how to build some benches so they gather up some wood left over from building the tree house and some tools and get to work. You go out looking for Adam and Aaron to tell them it is time for lunch. They are out at the back of the property building the benches when you walk up to them.
You notice they are using the power saw. (Red arrow in picture.)
You ask the boys about the saw. Adam says, "We know what we are doing and no one got hurt."
