Reminds me of the time I was about 6.
My mum & nan both used to swear in Danish (nan was a Dane) thinking it was ok. Great granny from Denmark was over on her annual visit & I dropped the big tin of buttons we used to play with as kids, they went everywhere.
Me, well you guessed it, stood there & swore fluently in Danish – apparently Great granny’s face was a picture & my nan & mum got a telling off for swearing in front of me. :lol:
