So I have some family visiting. I rent my house from my parents (with a discount) and help upkeep the property and pay the bills.

My parents don't mind and I am grateful for a place to live for cheap. Sometimes when family visits they stay in my house in the guest rooms. This happened recently and all the other rooms in the house were being stayed in by my aunt uncle and 3 cousins.

There are 2 full bathrooms in the house (1 being mine) and another that's just a toilet. I came home from work and my younger cousin was coming out of my room the master which also has the bathroom connected in it. I was like "What are you doing in my room, please stay out of there" and he explained he "Had to take a shit" and all the other bathrooms were in use.

I walked into my bathroom and of course there's shit stains on the toilet that he didn't clean.... And my room and bathroom was a bit of a mess so I didn't really want people in there.

I kind of yelled at him a bit about it and why he couldn't wait 5-10 min for one of their bathrooms but I was also flustered since it was my personal space and he didn't even bother to clean his shit. My uncle heard and got involved and he was getting mad at me saying we're family and it's not a big deal and we kind of just went back and forth until it fizzled out.

My cousin and aunt agreed to give me my space and not use the bathroom but my uncle was left kind of muttering under his breath, but I tried to let it go.

AITAH?
