railman Despite the fact I've posted here, none of these things irritate me enough to say they drive me mad. Nor does 'you guys' because, frankly, how else would you ask three or more people? 'You lot' 'You people' ??
'How are you all' sounds pedantic in itself as if the speaker will not lower themselves to casual or common usage - which is what so many of these phrases are.
I deplore the current fashion for, 'I was like...' rather than 'I said...' but these things come and go and I won't let it annoy me enough to mention it to the speaker (currently my grandson) as it would upset them.
Nor does the constant use of 'you know' often without the speaker even being aware of it, fall softly on my ears.
But then who am I to criticise?
As an English and Creative Writing teacher, I used to tell students that what we write and how we write it is dependent upon the situation.
Academic work needs a totally different kind of language to a novel.
The English we write is different to the English we speak.
Speech is different to narrative. Slang and dialect in narrative is wrong, in the spoken word it isn't.
Perhaps I should also remember that writing long screeds in a forum is irritating to the reader (if any).
