Well, what did they say when you told them thats not on!?
Well, nothing, I havent actually talked to them about it
Fuck off and talk to them and then come and complain
Well, the reason the question ' What did they say when you told them,,, etc" is patronising rather than good and relevant, is that it assumes the course of action proposed by the person posing the question is the only possible one. So it comes across as rather sneery - 'why haven't you already done this absolutely obvious thing,[you idiot]?' And there might be a number of reasons why. The OP might genuinely not know that a situation is unfair/unreasonable/someone is being vile; or the person being vile is terrifyingly violent/mad/Mafia-connected; or the OP has problems which might prevent them marching up to the person and demanding they desist.
But if you were to ask, "Have you had a chance to talk to them about it, OP?" - well, that is a more helpful, open question, is it not? The OP might then say, no, and I'm scared to because....or No, and I don't know how to go about it without causing offence, ...or No, because I can't leave the house because of crushing agoraphobia...and then posters who were genuinely interested in the OP's dilemma might have something useful to add.
Does that help clarify it for you? HTH.
