I am looking at Text C and E and comparing the way in which they express their language through two way communication.
To communicate Text C uses high frequency lexis in a polite tone because the form is a children’s book and the target audience is children. The book uses simple terminology perhaps so kids can read the book themselves or maybe it’s purely so they understand the content when guardians are reading it to them - this explains the polite tone the characters possess 'Good afternoon'; its sending a positive message to the younger generation to preserve and develop their manners. During the convocation between Mr Muddle and Mr Bump in text C, the relationship between the characters becomes apparent - 'Do you know what my name is?' 'You're Mr Carefull' . The characters obviously know each other yet due to the forgetting nature of Mr Muddle the answer he gives to Mr Bump is incorrect even though they may be well acquainted.
Text E also uses high frequency lexis but in a subconscious manner - as the text is in the form of a transcript that’s not been rehearsed (convocation between a customer and vendor) so it is full of terminology people use in day to day speech, this illustrates why fillers 'er', pauses and overlaps are present. The two subjects are not very familiar with one another but have a relation towards the content of the matter at hand (newspaper account). This could be why subject B hazards a guess towards the title of the enquiry 'It's 135 Penny Street isn't it'.
