If I was the dad of the kid you beat - you'd be getting 10 times as worse as you deliver, and since these days I'd be sued for it - I'll make sure I get my money's worth.
And you'd probably be justified in doing so, unless your kid was in the wrong attacking my kid or anyone else.
This I can understand and have no problem. The image I had of the last post is a 200 lb man slugging away at a 110lb 12 year old(and the reason for my rather harsh reaction).
