The Dreaded Detention Class

I hated detention class. You were kept in after all your friends had gone home and had to spend an hour sitting up straight on a hard chair, arms folded. Then, of course you were under the beady eye of the teacher, who also probably hated being there. One of our teachers used to keep a slipper on the desk during the detention class, and made it clear that she was prepared - if not keen - to use it on any girl who misbehaved!
Before that, of course, you have to let your parents know by giving them the detention slip, and that could have very unpleasant consequences. The joys of detention!
