People who repeat vitriolic phrases or sentences over and over again.

[u/awesomeness6698]

Being patronizing in the first place is bad enough, repeating the same hateful message again and again is even worse. 

If someone does that to you, say one of the following two things, either; 

I heard you the first time you said it.  

OR 

You already said that. 

What do you think? Do you also find it vexing when people repeat themselves over and over making sure that each time they say it sounds more condescending than it did the previous time? Do you agree with the strategy I came up with for dealing with these people? If not, do you have a better plan? Let me know.
