One of the bigger questions is: How long was David in his room? was it 2, 3 or 4 hours where as his mother did not check on him? The longer the time the more distance he was able to run away. Also I can relate to this scenario if this is what happened. Twice my 10 year old son has gotten mad and he suddenly ran into the back yard. He once did it in the winter in the dark. He was upset about being corrected and just decided to run. Maybe David got mad after being corrected by his mother and decided just to run out of his house through the window? I don't know - hes only 6. Do 6 year old do this?
