Many times I swear without even thinking about it
It's just how I communicate, always had issues with it ... in fact one year I came home from the USMC, had XMAS at my Grandmother's House, now backstory, she had 14 kids, lived to 102 years old, I was dropping F Bombs without thinking and she put Ivory Soap in my mouth, took a hard squirt mid sentence
I get it with kids, but we are not emphasizing the swears, they just roll off, or out, so if you ignore it, the kids probably will too.. that tends to be my experience
You can always explain to them, how certain people talk in an not so polite way, but focus on the message and not an individual line or set of lines.
Even here, I write as I speak, so when you see me swear in print, that's how my head says the response... so I write the words just like any other, if my brain says, No Fucking Way, I write No Fucking Way... I don't say how do I adjust things for an audience I just flow ...
I had to write a 2000 word article, I just zone and when I was done, 2532 words wind up on the paper... it's a thing. But I do write different for them, and it's not natural. I have to do a lot more editing so the flow is correct because I don't speak that way.
