Okay, so I changed things a bit here to keep up the flow. In the original strip Susan makes her escape and is only caught and punished (most severely) later.
You might also be wondering why the girls are not wearing those little plaid skirts we have grown to love on catholic schoolgirls. It seems that in the last year of school, what the Brits call - for reasons I cannot fathom - the Upper Sixth, girls were allowed to change from their cute plaid uniforms into a more sensible outfit befitting their age. This is the outfit the girls are wearing in these strips.
So called senior girls were also not expected to raise their skirts for punishment, in contrast to the other girls who took theirs across their knickers. And the cane was used instead of the paddle.
