I’ve had problems with roommates on the spectrum that I rent out to who seem to think that they should ask for explanations of rules as a way of trying to argue. Normally I’d assume they’re just trying to be jerks and look for backdoor ways of arguing or “concern trolling,” but I’m open to the slim possibility that they don’t actually understand or this is their way of trying to discuss it.
They also try to argue and play lawyer games when it comes to guilt. If I see a plate in their room, they’re getting fined for eating in there. It doesn’t matter if it was someone else because they allowed it.
It occurred to me that they might genuinely not understand what is going on.
If your tenancy agreement with them is repeatedly getting broken by them disregarding your rules, kick them out.
