In my humble opinion, mirroring will only work with difference of opinion or fights, not when someone is going through a rough time. I mean just picture the conversation
Person#1 My father is very sick, and is in the hospital
Person#2 so if i understand your father is sick and in the hospital
Person#1 yes why are you so cold about it?
Person#2 so you’re asking why I’m cold about it
Person#1 are you normal?
Person#2 you’re asking if I’m normal
Person#1 PUNCH
Person#2 PUNCH (he has to punch back, his mirroring)
I think you get the point
