I had to kneel above dried corncobs once, because I've done some seriously bad shit, I never done something like that again...
Well, I do think my mom exagerated on that punishment, but I don't remember being hit since that time, I done errors after that, obviously, but none that was stoppable or that I had conscious it would have no reward in the end, so I think that beating realy was good for me.
With this, I am up for the back of the school beating here in Brasil as well.
