Input: Text: this happened a while ago and will haunt me for the rest of my mortal life. in school i do dt food (cooking, nutrition etc) as a subject. before we had been making jam tarts and i had some jam left in a jar. being the lazy person i am, i left the pot in the bottom of my bag and didn't take it out because it was so buried in all the crap in my bag. fast forward by about two weeks (yes two weeks) and i still hadn't moved my jam. i got into maths and, being the last lesson of the day, i chucked my bag into my desk and opened it up. oh crap. my jam jar had exploded in my bag. i went silent then shouted "for fucks sake!", grabbed my bag and just pegged it out of class. no one had said a word to me as i left. i was seriously pissed at this because there was just jam everywhere. on about 4 different work books, a text book, my calculator, all my stationary and my phone and house key. i was going in and out of class getting all my stuff. i had to put all of my jammy stuff in an empty locker in a plastic bag just to stop it leaking. i sorted all my stuff out and got to work getting the jam off. as i worked i was quietly cursing loud enough to hear, repeatedly saying things i'd never say in front of anyone in any of my wildest dreams. suddenly, i looked up. there were about 10 different people just staring at me. great, it was open day. the one day of the year when there are parents and five to ten year olds milling around the school, and there were three sets of parents, 4 kids and a sixth former guide just staring at this angry thirteen year old who has jam all over his hands and all his stuff outside a maths lesson cursing to himself. the parents looked horrified. i just stared them down with the most emotionless stare known to mankind and the sixth former hastily moved them on. bet i won't be seeing those kids at my school any time soon. finally i had cleared everything up. i put everything into separate bags and left them outside my class. then i realised something else. it was a revision lesson for an algebra test. and i'd missed half of it. (i ended up getting a crap mark funnily enough). the lesson passed and i didn't talk to anyone. so the end of a very jammy lesson came about and so i had to talk to my maths teacher. being the best teacher i've ever had, she helped me clear my stuff away, lent me some tissues to wipe away my jam that had formed a second skin over my hands and just asked me to tell her what happens if something like this happens again, god forbid it. then came to the awkward convo with my parents. i've been reduced to a crappy old reebok bag for the last months and a half and am still getting weird looks... i've not eaten jam of any sort since. i spent too much time getting old jam off my hands at home and my books are still sticky from the jam and i can't get it off.

TIFU by leaving a pot of jam in my bag for too long and finding out too late...
