I suppose I've got what they call a generic English 'received pronounciation' accent. I live in Sarf London now and some of the mums at my son's primary school have said to me 'Int you well spoken?' I never think I'm posh but they do take the pish out of me and say I sound like royalty.
However, having been born and initially bred in W. Africa I can easily slip in to a form of 'Pidgin' English street slang (which fills my highly educated mother with dread even though she's been known to talk it too).
My English Grandmother was from the NE so I got an early insight in to regional dialects when I was little (even though she'd been in London for most of her life, she still had a trace of Durham), I think I was the only kid in my primary school in West London calling everyone 'pet' or 'hinny'
My older kids also do all that 'yoof' speak. 'Buff tings'; '(al)low it'; 'Jam your hype fam'...I find it quite amusing. How language evolves interests me.
