Input: After the thousandth petty argument with my roommate, I figured I should bring one of them over here and see what opinions I can get. Warning; extremely petty.

Backstory: I (23M) live with a roommate (23M) in a two-person student apartment. We've known each other since we were kids, and we're currently both studying abroad for our master's courses. We're good friends, but we argue a lot about stupid things, even more so ever since we started living under the same roof.

The best system that works for us is having a structured system of turns whenever we have to do household chores. I cook one day and he washes up, then he cooks the other day and I wash up. I clean the place one week. He cleans the place the other week. And so on. We try and keep these things clear and agreed upon in advance to avoid arguments.

I have slowly accepted that I have much higher cleaning standards than he does. Every Sunday when it's my turn to clean, I spend 3-5 hours straight and am *somewhat* thorough (or, the word my friend likes to use, "obsessed"). When he cleans, he's done in an hour tops. He wipes off some kitchen surfaces, vacuums the fitted carpet, and washes the floors.

After he's done cleaning, it's very common for there to be visible oil stains around the walls in the kitchen, bits of food caked onto the counter, soap scum in the drains, pieces of onion/garlic skin scattered in the cupboard or on the floor, pubic hairs around the bathroom floor, facial hair around the bathroom sink, dust on the surfaces he didn't bother to clean, etc etc. All of this gets on my nerves, but he says he doesn't care about it. I'm no cleaning fanatic or anything (in fact, I don't enjoy cleaning at all), but I like the *results* of cleaning and enjoy living in a well-kept place, so I do put effort into it.

Either way, he has different standards of cleanliness and I've come to accept that if I want the place to be clean enough, I'll have to put in 4x the amount of time he does to get it to that state. Everyone has different standards and I can't force him to abide to mine.

Now for the argument. My parents or his parents sometimes come over to visit from our home country and stay on our sofa bed. They generously help us out with the cleaning when they come. Whenever it's my turn to clean and my parents are over, I usually help out with cleaning too, but each time, my roommate insists that I didn't help enough and that it doesn't "count as a turn", so I would still need to clean the next week.

Last week, my parents came over again, and I spent around 1h30min helping them clean. I vacuumed, did the bathroom surfaces, washed the floors, and changed the vacuum cleaner bag. Of course, an hour and a half of cleaning is not as long as I usually spend, since my parents helped a lot too. Today comes, and the same thing happens. I tell him he should be cleaning, he says it's still my turn because my parents were over last week to help. I get a little tired of this excuse (or at least, what I perceive to be an excuse) and have a go at him.

His arguments are "you didn't do everything by yourself last time, your parents helped you" and "you can't just change a system - when parents come over the previous times and helped with cleaning, we never skipped a turn".

My main argument is that, despite having help, I still spent more time cleaning last week than he does on average when it's his turn (which he didn't deny). He now refuses to clean, putting me in a position where I have to either clean for this week too or put up with a dirty house for another week. As someone who is genuinely quite tired of having the burden of a lot of the house upkeep being on me and is also busy with other things today, I really don't want to be the one to clean again, so I'm quite annoyed.

TL;DR: My roommate and I have a turn-based weekly cleaning agreement. I have higher cleaning standards than him so I spend around 3-5 times the amount of time he spends cleaning when it's my turn. Last week, my parents came over and helped me with the cleaning. Despite the help, I still spent more time cleaning than he usually does. He still insisted that I didn't do my due for that week since I had help and that I should spend my day cleaning again this week. Am I the asshole?
