Sadly, the Sussex dialect seems to have died out but I can remember relatives living in the country having a soft rural burr, pleasant but not as strong as those further west. (I was a Brightonian towny where speech was closer to London, including some use of the rhyming slang).The idioms seem to have gone too but we used to call connecting lanes or alleys between walls or hedges "twittens" and call out "fainites" as a truce term when playing games. I still say "It's black over Will's mum's" to call attention to dark sky threatening rain although I have no clue to the identity of Will. Not sure if the use of "kiddy" to refer to a youth or indeed male of any age is local to Sussex only?
