There's a difference between being posh and being rich.
I was planning to go into law or politics. I was well known for my public speaking. I went to an all-girl boarding school with uniforms. It was very posh for someone like me who came from a world where my parents showed beagles and sold dog products out of a yellow caravan.

'Downton Abbey' about upper-class posh people: of course it is.
