Well, I'm from Liverpool, UK, and that's kind of an ethnic origin all of it's own!!!!
But there's a bit of Irish from all sides (look at the surname for goodness' sake!!) Some would say that's why I'm always talking, telling stories, singing, dancing and laughing (even in work - I work in a library!) However, we don't want to reinforce stereotypes, do we!!! Besides, there's European stuff in there too, or did the Irish stuff frighten it away?
