Actually I cannot spend more than a few minutes with someone with an accent and somehow I taken on the lingo, I've been told I am a natural mimic.
I've no trouble regurgitating an Irish or Scottish Accent, Liverpudlian, Gordie, Welsh and I've been told that I sing my country songs with an American Accent.
I have done a little Acting in the past, used to teach a little drama and role play here and there and as my brother lives in South Africa I was able to offer up a little Afrikaans. Not tried the Australian much but one day maybe.
I love playing around with accents as it helps with dialects in my writing so when I'm watching TV I sometimes try to copy the way people say things which can be good fun - I recently enjoyed watching 'Wild at Heart' (Leopards Den) and loved copying the many accents in that.
I love to tease with a french, spanish or Italian accent...have fun with it, I say.
