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.
Also known as the .30-30 Winchester. I have no idea what a hunting rifle cartridge has to do with Russia. Perhaps they were thinking of the 7.62x54R (used in various Russian military rifles) and mistyped?
You mistyped. The 7.62x54R is a Russian military cartridge used in a number of rifles, perhaps most famously the SVD.
