I don't understand what you are saying.

I don't quite understand.

I can't understand what you're babbling about.

I don't understand, Monsieur.

I don't know what you are talking about.

I'm afraid I don't understand.

I don't understand your approach.

I don't know what you mean.

I couldn't understand you.

You said you like me, you love me

I don't understand what you are saying.

I don't care what you say, understand? Go on, spy on me!

You don't understand anything. Don't talk nonsense. Listen.

Stop shouting at me. I can't understand a word you're saying.

You don't understand a thing.

That's as clear as mud.

Not only don't you have any scruples, you don't have any brains.

You understand what they say, don't you?

Have you understood what I said to Palucci? Enough.

I don't understand the language and it may be important.

I don't know what you mean.

I don't understand what does it. What did it for Johnny?

He says he doesn't know what you're talking about. There are no other people.

Tell me what's wrong. I can't understand you.

Couldn't understand a word he said.

Don't you see why I had to?

Do you understand me?

So I said, What? You don't understand these screens and you keep staring at it for two months? What for?

What stuff? I don't know what you mean.

Do you know what you are saying?

Or, Why are you doing that? I don't understand.

Tom always speaks in such a low voice that I can barely understand what he says.

I don't know why.

I know nothing.

I don't understand anything, but I worship you.

I don't understand why you brought me here.

I don't know what you mean by that, dear, I'm sure.

I mean, there we are.

Yeah, say you know all about everything don't you?

You're no veteran.

What would you know about scenery or beauty or any of the things that really make life worth living?

On, I don't know anything anymore.

I don't know anything.

I see now what people mean when they complain about your bad manners.

I don't think I get you, Mitch. Do about what ?
