I might get flamed here but would like to get some mum's opinions.
Aibu to not instantly reply "I'm not their mother" on the very rare occasion that a stranger who I will never see again refers to me as dp's children mum in passing ? My friend thinks I am because she would hate for anyone to think anyone else was her kids mum.
Dp's children find it funny, if it bothered them I would of course correct it. As we are different races and they call me by my first name it happens very rarely, maybe once every 6 months.
