M:  Oh look, this isn't an argument.
A:   Yes it is.
M:   No it isn't. It's just contradiction.
A:   No it isn't.
M:  It is!
A:   It is not.
M:  Look, you just contradicted me.
A:   I did not.
M:  Oh you did!!
A:   No, no, no.
M:  You did just then.
A:   Nonsense!
M:  Oh, this is futile!
A:   No it isn't.
M:  I came here for a good argument.
A:   No you didn't; no, you came here for an argument.
M:  An argument isn't just contradiction.
A:   It can be.
M:  No it can't. An argument is a connected series of statements intended to establish a proposition.
A:   No it isn't.
M:  Yes it is! It's not just contradiction.
A:   Look, if I argue with you, I must take up a contrary position.
M:  Yes, but that's not just saying 'No it isn't.'
A:   Yes it is!
M:   No it isn't!
A:   Yes it is!
M:  Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes.
(short pause)
A:  No it isn't.
M:  It is.
A:  Not at all.
