Just a question I have never had a satisfactory answer to.
I pick up accents ridiculously quickly. For example, when talking to my friends in Canada over the phone I will pick up a Canadian accent, I'll suddenly notice I am saying "aboot" or something and then become very self-conscious.
Similarly, when my Welsh grandfather was alive I would go Welsh over the phone.
My cousin and her husband moved to Australia 9 years ago. Her husband developed a full on Ozzy accent within a year, yet she still sounds very English, there is not even an Ozzy twang.
What about you guys? And any thoughts as to why this is?
