You think you’re having an open conversation with someone.
There’s some back and forth.
You have your say, and then he has his.
And then – dangit – you suddenly realize it’s one of THOSE conversations.
The other person isn’t really listening to you at all. He’s just waiting for the right moment to jump back in to push his own opinion.
While you’re talking, he’s essentially tuned out, marking time, and waiting for you to stop talking. He’s completely deaf to your side of the “conversation”.
