Come in.

  Ah, Is this the right room for an argument?

I told you once.

  No you haven't.

Yes I have.

  When?

 Just now.

  No you didn't.

Yes I did.

 You didn't

I did!

 You didn't!

I'm telling you I did!

 You did not!!

Oh, I'm sorry, just one moment. Is this a five minute argument or the full half hour?

 Oh, just the five minutes.

Ah, thank you. Anyway, I did.

 You most certainly did not.

Look, let's get this thing clear; I quite definitely told you.

 No you did not.

Yes I did.

  No you didn't.

Yes I did.

  No you didn't.

Yes I did.

  No you didn't.

Yes I did.

 You didn't.

I did.

 Oh look, this isn't an argument.

Yes it is.

  No it isn't. It's just contradiction.

No it isn't.

 It is!

It is not.

 Look, you just contradicted me.

I did not.

 Oh you did!!

No, no, no.

 You did just then.

Nonsense!

 Oh, this is futile!

No it isn't.

 I came here for a good argument.

No you didn't; no, you came here for an argument.

 An argument isn't just contradiction.

It can be.

 No it can't. An argument is a connected series of statements intended to establish a proposition.

No it isn't.

 Yes it is! It's not just contradiction.

Look, if I argue with you, I must take up a contrary position. 

 Yes, but that's not just saying 'No it isn't.'

Yes it is!

  No it isn't!
