I remember a confrontation I had with my old man at about that age. Don't recall what it was over. His response was "I brought you into this world. I can just as easily take you out." By the look in his eyes I could tell he was not jokin' around. It must have worked. He taught me a trade that kept me busy as an operating engineer for 39 years.
As I'm not his bio-dad (been with him since he was under a year though), I can't really say that. The wife however, has said that a few times to the boy... and she wasn't joking either. Kid was good for a long time after that. :)
