Is this rude? Women to women opinion.

So my boyfriend and I rent out our basement to an older couple and there young infant of a few months old. I think it's rude that they expect me to always wash there dishes.. I HATE that. They have never once washed our dishes like really? I just washed mine and guess who comes upstairs with more filth? The lady sits at home all day on her ass as I and my boyfriend work my tail off. Is this rude to a degree or what? I'm not crazy but this is rude and I know it. My boyfriend thinks I'm bitching but in reality it's wrong and needs to be addressed.
