What if it was your Mrs or daughter getting hassled by some nob head, would you not hope someone worth anything would help out?
Last rumble i had, it was none of my business, but I can't fecking stand bullys, so I got involved. Bruised next day, chipped tooth for rest of my days, but I stopped some poor kid getting picked on. And I could look myself in the mirror (through the non swollen eye! ?)
