There are several differences between the two texts, for example, Text A is taken from a 1980's play called 'Educating Rita', and so therefore has the purpose of entertainment, however Text B is simply a transcript, and so therefore has no other purpose thanto bore me to death. In Text A, 'hedging' is used, and the audience are aware of this, and so it creates comedy value and is therefore helping the text to achieve its purpose, to entertain. An example of this is when Frank says 'But if you're going to write this sort of stuff you're going to have to change'. By employing the lexical choice of 'change' he is implying that Rita would have to alter her methods, rather than being bald on record and confronting her about her clearly very poor literacy skills. This suggests a friendly relationship between the two characters, as Frank avoids further upsetting Rita. Good old Frank.
However, in Text B, the regular interruptions which have been transcribed also suggest a friendly relationship between the Tutor and Julie, as it is regularly used to symbolise Julie's agreement with her tutor at given points. This suggests that Julie has a very positive attitude towards her work, as she simply agrees with her tutor and understands where she has to make alterations within her work. Furthermore, there are several short pauses within Text B, as breaks are taken for characters to correct themselves or change the way they were saying something. This also suggests a friendly relationship, as they have time to stop, or alter what they were saying, which creates the atmosphere of a general chat.
Moreover, Willy Russell tries to create the idea of spontaneous speech within his play to force its ability to represent a real life scenario and therefore make it believable. When Rita says 'No, come on come on' is an example of repetition being used. Repetition is used in everyday conversation as someone is distracted or decided to alter what they plan to say next, and so the use of this within a play creates the idea that the chat taking place is realistic.
