This is nonsense. Fighting at school deserves suspention. Who cares that he was suspended. Now he gets a 3 day vacation while all the rumors of what a badass he is at school. When he returns, maybe he can live a life being left alone.

If I was his father, i would have picked him up from school, told the principle "yes, Hes Mine, and I live him and proud he stood up for himself, and expect him to do it again" Then I would take a few days off, go fishin with him, and explain the difference between the honor and integrity he displayed in a tie of duress versus a stupid rule the school has inn place for fighting.

I would also help him learn ways to sulence the bullys quicker and stealthier.
