Do your parents curse at you or around you?

I noticed my dad and his girlfriend curse around me a lot more than when I was a little girl. I first met her when I was 10.
Like my dad she is blunt and straightforward.
My dad said, “You’re not a little girl anymore anymore. You’re a young woman not. We can say this around you. You’re almost an adult.”
Why do they do that’s. They’re both straightforward and brutally honest.
