I was not arguing the case for either sexual equality or difference in an overall sense, but just on the equality of discipline and punishment that could be seen by both girls and boys to be equal. But obviously with some allowance made for differences. eg skirts/trousers.
Where the misbehaviour is exactly the same, then the same punishment, but in most cases although the offence may be the same it would be done in a different manner. Boys are usually “in your face”, whereas girls are more subtle (or devious )
