Your step son Dimitri is a very bright 12 year old who has a real interest in things electrical. It is 1975 and you have purchased a new color tv. The old black and white tv worked but the picture wasn't very good and your plan is to have it fixed and put into the gameroom downstairs.
Being so good at electrical stuff, Dimitri takes the back off the set and is toying around with the guts of the set. He sees a tube not burning as brightly as it should and proceeds to take things apart to change the tube (He has a box of junk parts for just this type of thing!!)
He didn't ask permission to do this by the way.
Are you going to be "taking him to the barn" for this?
