Welcome back to FR.....but your statement is the first I’d heard of that theory.
Twenty years ago when I was an 18 year old volunteer firefighter in our small town, we were dispatched to a home fire in which a small girl was trapped. When we arrived the entire house was engulfed and the roof had caved in, and there was nothing we could do to save the child. My father—a sort of gruff, 300 pound guy—was the fire chief and had to investigate the fire only to find out that the 5 year-old brother had started the fire by playing with matches. I’ve never before or since seen my father cry like he did that day.
