So I (23M) live with my roommate (22M), let's call him Adam. We’ve been sharing an apartment for almost a year, and while things have mostly been okay, Adam can be... eccentric, to put it mildly.

We split chores 50/50. I do dishes one week, he does them the next. Recently, I had a rough week at work, was running on no sleep, and Adam had apparently cooked a five-course medieval banquet and left all the dishes for me. Whatever, I suck it up and start doing them.

Then, two days later, I come home from work, and the living room smells wrong. Like, horrifically wrong. I walk in, and Adam is sitting on the couch looking sheepish. I ask him what the hell happened.

He tells me he had "an accident." On my seat. The armchair that I bought, that I always sit in, that he never uses. When I press him for details, he tells me he had some bad tacos, didn't make it to the bathroom in time, panicked, and sat down to "try and hold it in." Yes. That was his plan.

He shat. In. My. Chair.

Then he tried to clean it, but it still smells, there’s a stain, and honestly I just want to throw the whole thing away. He shrugged it off like it was no big deal. No offer to replace it, no deep cleaning, nothing.

So I told him, flat-out: I'm not doing your dishes anymore. You crapped in my chair, Adam. You broke the sacred roommate code. You don’t get clean forks from me anymore.

Now he's sulking and saying I'm being immature and making a big deal out of "just an accident" and that I’m "weaponizing chores" to punish him. Our other friends are kinda split — some say I'm justified, others say I’m being childish and should get over it.

So, Reddit... AITA for not doing the dishes because my roommate shat in my seat?
