Please give an example of dialogue peculiarity of Harold Pinter's The Birthday Party?

Harold Pinter uses silence, stream of consciousness, empty
repetition and confusion in his dialogues. He does this to mirror the unreliability of
language and truth. This goes for truth in general. He would say that what is true for
someone may be false for another. This also illustrates how conversational language can
be confusing. In everyday language, there are pauses, incomplete sentences and
unfinished thoughts. Pinter tries to capture this not only to be realistic but also to
show how language can psychologically represent ideas and
feelings.

For example, in The Birthday
Party, repetition is a work when Meg serves Petey corn
flakes:

readability="5">

Meg. Are they
nice?

Petey. Very
nice.

Meg. I thought they’d be
nice.

They carry on friendly
conversation but it is empty. There is no need to repeatedly confirm that the corn
flakes are nice. They’re just corn flakes. This reflects the emptiness of their lives
and their relationship. “Nice” is repeated in each line. There is no substance to this.
It is empty speech like answering “How are you” with an obligatory and automatic “Good,
how are you?” The speech is just ritual repetition. Neither of them cares about the corn
flakes. Meg particularly seems to always speak
absent-mindedly.

McCann uses repetition to symbolize his
own problem with what he and Goldberg must do with
Stanley:

Let’s
finish and go. Let’s get it over and go. Get the thing done. Let’s finish the bloody
thing. Let’s get the thing done and
go!

There is also the scene
where Goldberg and McCann harangue Stanley with an endless series of advice, most of
which are clichés. “You’ll be a success.” “You’ll be a mensch.” They are mocking
Stanley, psychologically playing with his mind. Just as Meg and Petey did not care about
the corn flakes, McCann and Goldberg do not intend to help Stanley “get better.” Meg and
Petey were in denial. But McCann and Goldberg are engaged in psychological mind
games.

Stanley appears to be stuck in the boarding house.
It is comforting but somewhat of a prison. This paradox is paralleled by Goldberg and
McCann’s intentions. We can’t ever really say for sure if they intend to hurt or help
Stanley. Are they hit-men or avant-garde therapists? Pinter shows how language can
prevent rather than facilitate meaning.

On the other hand,
the rising intensity and increasing confusion might symbolize Stanley's rising anxiety.
Conversely, when the dialogue is simple and slow, Stanley is calm. If this is the case,
then Pinter is showing how language is unreliable in the words themselves but can
occasionally communicate through intensity and emotion.
