What little things do you bicker about?

We do argue over cleanliness sometimes. My partner isn't a very messy person or anything and I don't have to have spotless living space to be happy. I do think that it's OK to be a little messy but I think after awhile things just need to be straightened up like once a week or whatever. Sometimes I get frustrated when things have been strewn all over the place for a few weeks and haven't been put back into their original locations. So I start cleaning and organizing and then I get yelled at for cleaning up because they were going to do it, or they'll never be able to find anything later. I don't see how that would be an issue of course if things were just kept where they should be in the first place but I guess that's just my way of thinking.

Ooooh...lots. And some of them are rather silly. Like leaving unwashed mugs in the sink, not putting things back in their proper places, waiting for me to make hot drinks (he would rather go without), forgetting where he last place something - the list is endless!
