My family are all Irish so sometimes that accent shines a bit, my mums side all have Belfast accents but they have been softened a bit from living in England. My grandads is funny he'll pronounce flour like "flur" or he'll use the I in italian like "eye"talian.
But my grandparents on my dads side have proper Irish accents so they pronounce T's a lot like "ooh, i wish you was Cat-lick" or "you want to watch him hes a teeth, that boy."
And a lot of my mates are Glaswegian and so many times i have to interpret for them.
Accents are funny things
