Jumping up or moving when you were getting caned was dangerous because it might earn you extra strokes. Also, your classmates and friends would tease you if you did not take your caning stoically. If the cane is to be used at all it needs to be used well. It is not possible to cane too hard. Our geography master was known for the severity his canings. In five years he never caned anyone in my class and very few if any in other classes.
