Input: Text: this didn't happen today, but my friends brought it up and i thought about tifu.

here is the tifu.

my school has a rule that you must change out of your sport uniform after pe at break time. this happened at lunch.

there are three sections to the change room. the sink, the urinal and the toilets. its also has automated soap dispensers and hand dryers
i usually change next to the wall opposite the sink, but today it was crammed with my classmates so i decided not to change there and to change at the sink. i placed my stuff near the sink and i always put my shirt on first. my clothes are in a messy pile, so i shift my shorts out of the way and i hear a buzz sound. i look to the right and i see that my pants have soap on them. i had place my pants under the soap dispenser. i call my friends who were waiting outside the change room. they laugh, say how the fuck did u manage this and leave. me, being an idiot, tried to was this soap off. i have a lot of bright ideas like this. so i placethe pants in the sink, and try to turn the tap on slighty, so i can take out the soap which is now in the fabric of my shorts, but i put way too much power and turn it on fully. now my shorts are soaked. great. there is still 40 mins left in lunch. i show my friends again, they tell me to dry it on the ledge of our deck, they finally said something useful. the deck is elevated about  two metres above the dirt ground, because it is on a hill. lady luck must of hated me, because the second i place it there to dry, it slips off the deck onto the dirt ground. i guess i should of thought about it more. at that moment, i knew those pants weren't going to be worn today. i  placed my pants in my locker and moved on with lunch. this time, persistence  is futile. 

40 minutes later, i have my books and everything, for my japenese class but i am still out of uniform. i start my walk to class, people asking me why im out of uniform. while im walking,  a male teacher walks past and picks up on thisinstantly and asks why i am out of uniform. 

stupidly, i say " i wet my shorts" . i can't be certain what he thought, but he gave me the wierdest look. my friends never let me forget these events. and i have a feeling reddit won't either , but meh.
