I was then in 2A at Junior school in 1985 and I was then 9 yrs old and like most of the other boys in the class had never had the slipper. We were being taken by a student teacher, I guess now was between 19-22 years of age, About 3 boys did play the young teacher up a bit!. I think our normal class teacher did tell him to do this, He the student teacher, told us that all the boys would get two of the slipper each to teach us a lesson.
