Incredibly sorry. I wasn't a bad kid by our schools standards so I got away with murder really because there was always someone doing something worse so I just flew under the radar. The one thing I am truly sorry for is a 3 month period where my sole purpose was to make our maths teachers life hell. She was a newly qualified teacher from a wealthy background who was very proud that she had come to work in a failing school in a deprived area, she boldly stood there on day one and proclaimed that this was her dream job and that she would be the one to get us interested in maths. Dream job? That seemed like a challenge and for 3 months my sole purpose became to ruin her dream. It started off fairly tame in my eyes with a question about how many generations of her family had practiced inbreeding to produce something so odd looking. When that made her cry I realised I could rattle her easily.
Over the course of a few months I locked her in a store room, co-ordinated a full class walk out of her lesson for no particular reason, hid all the textbooks, sneaked into her class at lunch time and changed her screen saver to something highly inappropriate, stole her diary from her desk and photocopied a page about her finding another teacher attractive and proceeded to distribute it to the entire school, she left the class room one day and I locked and barricaded the door so she shouldn't come back in, hummed like a fridge throughout every lesson, I swapped the family pictures she had on her desk for Hitler and Mrs Thatcher, wrote "Miss Potter eats babies" in permanent marker on her white board - this caused far more upset than I predicted, make of that what you will, I hid in a cupboard for a full lesson then jumped out at her a few minutes before the end of class and nearly gave her a heart attack, drew very crude caricatures of her on every page of my exercise book, she binned it so I went on strike claiming she was censoring my creativity, pretended to be asleep in her lesson, she didn't mind this at first as it gave her some peace and quiet until I pretended I was having nightmares and started rolling over the floor screaming.
I could be here all day to be honest but eventually, she came in one day and looked incredibly rough. Normally she was very well presented so this immediately caught my attention and I accused her of being a dirty little stop out saying she must've been up all night with Mr Jones (the teacher she had written about) and she burst into tears, screaming about how she hadn't slept for weeks and couldn't cope with me anymore and she stormed out the class and never returned. She was replaced by the schools head of maths who I really go on with so I went back to being well behaved and just kept my head down and got on with it, eventually did okay in the end of year assessments. He said he couldn't understand why Miss Potter couldn't deal with me and said she must not be cut out for the job if she needed to go on the sick for stress over me. He insisted it was mutual but looking back, I might've been a factor in that poor woman sacked from her dream job so, yeah very sorry about that.
