I never say mun't instead of musn't or must not. But I do always say cun't instead of couldn't or could not lol.

I was born in Scotland and lived in Manchester, Henley, London, Reading and Bournemouth before settling in Rotherham at 17 years old, 30 years ago.
My accent is all over the place and every now and then someone will ask me if I’m a cockney.

But yes, my accent changes depending on who I’m talking to and in what context. This isn’t a decision I make consciously. It happens without me realising.
