I went to a Catholic school and we had mass on Mondays... It was back in the year dot when we had to fast before communion and if you didn't have communion the teachers wanted to know why.....
We all brought sandwiches which we ate after mass in the classroom.
My mother always made my sandwiches from the remains of yesterday's Sunday roast and she liked fat so the sandwiches had fat in them and it made me want to be sick..
Every Monday I hid the sandwiches in the drawer under my desk.
One Monday there was a bad smell in the classroom and the teacher located the cause. She pulled out all this rotting stinky stuff from under my desk and I got into a lot of trouble. She belittled me in front of the whole class and they all stared at me like I had committed a crime :(
I have never forgotten it. I was about 8. I hate lamb :)
