I had a comment up here. I thought I was misreading the part about you fining your roomate. But after reading these other comments…

OP please explain what you mean by that. I assume you don’t mean your demanding actual money in these cases. Because as the comments point out thatd be very inappropriate.

With my own roomate if they leave a plate out they’ll get a lecture at most. I know they don’t intend malace with such things it’s just part of their adhd. They’d do better if they could.

I dont know your roommates circumstances, but can’t imagine a scenario where not putting a plate away is an act if malace against you.
