Only the teachers and sixth formers were allowed up the carpeted stairs, everyone else had to go around the bloody houses use the old service stairs (used to be a convent). This was automatic detention
The usual ridiculous rules of gym knickers, skirts having be within a certain length, etc etc.
We also weren't allowed to use the main gate, had to around the back to get into the building. Also automatic detention
Automatic detention for walking on various bits of grass or being in the chapel at the wrong time.
Had to write an essay about the evils of make-up in schools if you got caught with it.
No hair colour other than your own, (so no bottle blonds, highlights, bottle brunettes. One girl got in trouble for the natural highlights that her hair caught in the summer because they thought it had been bleached in. It had, by the sun.)
Knee length socks or tights all year round. No pants for girls.
Blazers all year round, to be worn at all times except p.e and break times.
No running in the playground.
Had to genuflect every time we saw one of the clergy (all the bloody time).
3 detentions equalled an automatic Saturday detention.
Train track braces had to be navy blue (to match the uniform).
I could go on!
