Is AUTHOR wrong in the post ? POST : I'm in a high school dormitory. I'm a year above the guy who decided to leave piss in the bathroom in the morning. Let's call him Piss-boi (17y/o). He's the second party.

So I see him walking out of our bathroom and was instantly alerted because his bathroom was on the other wing, so I peek into his stall to see that the lid was closed. Already suspecting the worst, I lift it, and I'm somewhat relieved that it was only urine. Still pissed me off enough to call him back before he left the bathroom entirely.

"Hey, [Piss-boi]."

He turned around nonchalantly. "What?"

"Come back," I replied simply, gesturing at the toilet. He did come back. He lifted the lid and went "oh" all dumb-like.

I asked him why he didn't flush. He said that the button required a hard press, and he pressed too softly. I asked him why he didn't hear the flush and he told me some shit about how there were too many people showering. I let him go with a warning, telling him that the next time he'd pull that shit, I'd expose him during evening registration.

Come evening registration, I bump into him by accident and apologize quickly. He tells me to watch where I'm fucking going. I look him dead in the eyes and ask him "you want me to say it?"

He goes "Oh, that time I didn't flush the toilet?" Mind you, he asked that while everyone was still talking, so nobody really heard him.

I nodded. "Yeah, that time. You sure, dude?"

"Yeah, totally."

Our dorm-parent takes registration, goes on about some shit or other, then goes "Does anyone have any announcements to make?"

By the way, I convened with a dormmate of mine who shared bathrooms on the same wing as me and he told me to go ahead. Emboldened, I went ahead.

I am met with instant vitriol. The guy didn't actually expect me to say anything, but I did. After registration, I'm approached by these guys telling me that what I did was bad and that you should have talked to him.

I simply responded with "It's not my fucking job to teach a seventeen-year-old to flush a toilet and it never will be."

Said seventeen-year-old goes petty and tries to engage me in some sort of diss-duel which he promptly loses, and before he can escalate, I walk out because I've got exactly seventy-nine things to do that are more important than trying to come up with some come-back to an infantile defence to why what he did wasn't so bad.

Maybe I shouldn't have reacted so strongly by exposing him when I let him off with a warning, but he was being flagrant about it in front of me, so what choice did I have? Leave him be, have him understand that it's something he can get away with and do it again? This has been a huge fucking issue in our dormitory, and people leave stuff worse than pee (shit, pubes to name a few) in those bowls. I'd love if we could take it more seriously, but the amount of people that jumped to his defence tells me one thing only: I'm one of the few people that takes bathroom hygiene seriously.

Tell me, Reddit. AITA?
