I use Britsh terms because I live and work in Britain. My husband and children are British and Scottish people.
I make my living working among British people. I need such a living, we rely on it to eat, so I adapt my spelling and adapt it well.
No one would know, when I write for my clients, that I was not born British.
My children call me 'Mummy'. They are British people, after all.
I do not correct them. Why would I? I do not live in America.
If I wanted them to speak in American accents and spell and say things the American way, then I would take up my mother's generous offer and come into my own and move there.
That is not the point.
I fail to see why this would niggle someone.
I am not bothered that my British children are not like me.
Oh, god, I hope they are not! I am such a dismal failure and now I age I am so ugly into the bargain! God save them that they are like me!
Would I wish they call me 'Mummy' and 'Bubby' as they do, but they have very deep Scottish accents. Really strong.
And from what I can hear, they are very 'working class' like DH.
Oh, dear.
Well, fuck it.
There's far worse in life than a fucking Scottish accent.
