I grew up in North Antrim during WWII, we didn't see
ourselves as particularly poor, but we had no radio,
and of course no T.V. and apart from infrequent visits
to the cinema we had no exposure to other accents.
The first time that I met someone from Cork, at the
opposite end of Ireland, he might as well have been
speaking Swahili for all that I could understand. When
I went to work in England I had a terrible time getting
people to understand ME, it took quite a few years to
rub off the rough edges of my speech, not that I was
ashamed of it , but you need to be able to communicate.
And yes, 'Darry' people do speak funny.
