[Duchess]

it works cause it plays on a simple factor.

You stick your hand in fire...you get burnt. Thus, you don't do it again for fear of getting burnt. That's the force behind physical punishment.

And as i said, she steals OTHERS stuff and break them as well as her own.

My mother recently bought something for herself... within 24 hours... it was taken without her permission by my sister AND BROKEN....

How do you punish that? no money? no computer? what? none of it works... she STILL purposely chops up her books with scissors and loses all the school supplies.
