The fact that you were downvoted so heavily for saying “two-sided discussion is good”, presumably because Americans got uncomfortable with the accusation that their government is writing their narrative for them, tells me that on this specific issue it’s most likely going to be an echo chamber

People have been hearing one side of this debate for so long that it feels kind of like a lost cause, to me. I’ve more faith that productive discussion can be had re: China than this war

Well yes, that was what I meant by “miscommunication”. Either the agent and flatmate didn’t understand whether or not they had the okay to enter the room, because OP went straight to work without informing said flatmate, or they Needed OP out of the room and OP was unaware. Not an “asshole” move, but certainly more ambiguous than they could have been about it.

I fully believe with better communication that either OP would have held off on taking a work call, because the agent couldn’t enter with them in there, or they would have come in the room even while OP was working.

NTA, but it sounds like you could’ve explained to your flatmate ahead of time that you needed to work and couldn’t be disturbed. Your behavior should not have been a surprise.
