Are adults not allowed to be childish and to like cute things? The older I get the more strength I'm finding to stand by my own childishness.

Sure, and the rest of us are allowed to find that fucking cringe.

Just use curse around children and explain how society handles curse words so they can learn.

I probably swear less since having kids and use more non-swearing expletives ("flipping heck", "crikey" etc.) in real life speech. Some of that inevitably bleeds into how I write online even though it's not directed at kids, just because language is habit-forming.

But I really, really hate the "f--k" thing. Either swear or don't. Swearing like you're trying to get one over on teacher is weird.

Who cares if they even are, who the fuck are you to prevent them from speaking how they want to

Sure, and you’re also allowed to keep that to yourself instead of being a moron about it

I didn't prevent anyone from sounding stupid.

I'll have to admit it doesn't sound great and fair, I assumed you were actively against people saying this like some other in the comments

I'm not against it per se, although I'm against most forms of censorship to appease religious or political pressures. I tend to assume people who self censor swear words are religious or dumb though.

Or just because you’re around kids
