Shutdown phrases
Thank you, I will take that under due consideration.
I can’t believe you suggested that.
Sometimes the best thing to do is to shutdown a conversation right then and there, without going into a debate over something, for whatever reason.
Most of the time the other person will respect that, happily or otherwise.
When they don’t, you need a shutdown phrase. The idea here is to trick your opposite numbers brain into thinking you said yes or agreed with them, without really doing that.
