I don't really think we have the same class structure over here. I suppose from a British perspective my family would have been working class (farmers, I think that's working class), but it doesn't really mean anything in Ireland or have any of the connotations it has in Britain.
The whole "class" thing was the most cultural fascinating thing about England, for me, when I lived there. As an outsider it seemed really culturally rich, although you guys on the inside might have a different view.
The closest I have is that I'm from a Bardic family, which still commands some respect in the Gaelic speaking areas.
