what you have written, icanhandthemback, reminds me of an incident when i was at school.
another girl, also a weekly boarder, told me that she had been assaulted by a local boy at the weekend. we were 13-14.
she was given to drama, so i was a bit dismissive.
i said if that was so, she should tell someone grown up.
she decided the only person she could tell was the priest, probably because he was the only man around, strange as that seems now.
i think she would have found talking to any of the staff too embarrassing. then she insisted that i had to be in the room while she told him, which i found embarrassing.
all i remember is saying she wanted to see him, then i moved to the window and stared out of it.
he said he'd ask a policeman whom he knew, for advice.
the priest came most weeks. next time he said that the policeman had said that it couldn't be proved, so no point in doing anything further. so that was that. end of.
they were different times.
i never thought of advising her to go to a doc.
at the time i was a bit annoyed by her involving me in it.
there were no matrons/ house mistress there. nor 6th form.
