Thank you

About "talk at" can an analogy would be when in a two-people conversation one person do most of the talking (aggressively) and desnt let the other party even talk?

Well, I had the same impression when I read meaning (you talk AT someone when you're angry with them), but I'm not sure if a native speaker would agree with that.
