I don't even know where a posh accent could come from for me. Nobody in my family talks with a posh accent, nobody I know at school or anything. My sisters even point it out sometimes when I say certain words (namely "awful"), and sometimes get me to talk to their friends on the phone so they can hear my poshness
We had basically a free in Welsh today even though our teacher was there but anyway we were talking about accents and how some peoples accents come out stronger when they're with different people and my friend Meg turns round to me and just goes CARAHHHMELLL
never going to live it down ellie, ever.
