Lumber
My friends and I in junior high set out to build a tree house in the woods. We needed wood for this job and I knew just the place to find it, under our deck. I don't know why I thought this was a good idea, but we pretty well emptied all of the spare boards from Dad's supply without consulting him. Looking back now, knowing how aware I am of my property and likely how aware Dad was, he knew all along. Years later he told me that he knew and there was no accompanying consequence. So stealing is ok. I kid.
