Soledad,
When I was School overseer I was always trying to get the sisters to think imaginatively like you and your mum. It was rare anyone tried. I'm glad some sisters tried to make the most of a misogynistic arrangement, good for you.
When on the school I used to try and incorporate lyrics from music that I liked, usually from the Smiths or Prince. It kept me and my other disrespectful friends amused. I also remember that while my big brother took the school I'd always use an illustration that took the piss out of him - it was nice slagging him off to a large group of people.
