Like all the Irish side of my family, I have a modest talent for languages and accents. My Irish aunties could recite funny rhymes, sing funny songs and 'do' a comic turn in any number of voices and accents.
My two Scottish nieces from the Irish side, when very small, had a different 'voice' for each one of their toys. The younger girl had a stuffed toy monkey, who had an accent just like a used-car salesman - dodgy and spivvy!
I'm just the same. It's very handy, as when I'm abroad I can pick up words like a sponge. And having lived in several parts of the UK, I find myself speaking just like the natives. At the moment I'm doing Broad Norfolk, having been here for forty years. It was also useful when teaching. If the class seemed to be losing concentration, I'd suddenly start speaking in another accent. They never knew who I'd be next!
