Shame and fear of father. I cannot imagine the beating I would have received for being arrested for fighting in public like that. Heck, he still may be able to do it.
I was raised with the words--just as many others here were--"if you go to jail, I will leave you in there."
That and "You'd better never get in a fight, if you do you'd better win or I'll beat your ass when you get home."
