I was there for over four years 1995-1999; 2 1/2 as a student and 2 as single staff.
Something to keep in mind when writing your book... The boys dorm and girls dorm were two completely different worlds. I believe the majority of the physical stuff went on with the boys. The girls were handled on a more emotional level. The physical stuff usually subsided within a few days after admission, with a few extreme exceptions. After that, humiliation was the preferred method. I do not use the word "abuse" as I was never in the boys dorm to witness what happenned. Only the boys would know the truth about that. I could never make judgement either way. However, I have learned in all areas of my life that the truth usually lies somewhere in the middle, once you take the underlying emotion and motive out of it.
