What they saidWhat they meant
"You're directionally correct"You're essentially wrong
"That was a good start"Now start over
"I don't disagree"I disagree, wrapped in a thick, obfuscating blanket of double negativity
"I agree with everything you just said"Except for your most important point, and I will indicate my disagreement through what I say next
"Could you repeat that"I wasn't listening
"Could you rephrase the question"I've been surreptitiously checking social media for the last 20 minutes
"That's a fair point"Now let me make a fairer one
"Let's explore the logic on that"You're wrong, and I’ll need to see ten pages that tell me why I am wrong before I change my mind
"Sorry for interrupting"I wish I had cut you off sooner
"That was interesting"That was a dumb idea, and I am changing the subject
"This will be quick"I have nothing to say, because I'm not prepared
"It would be great if you could..."Do what I'm about to tell you or else
