Pre-period diarrhea sucks enough already. Having to experience that uniquely painful and explosive situation anywhere is awful. Having to endure shitting your brains out in a multi-stall bathroom at work is almost unspeakably awful. But when you work in a school, and you have to share that bathroom with the 12 year old girls you teach, letting it rip while they cut class/apply makeup/take selfies/Skype boys a foot away... well, those are the moments there just are no words for.
