I think the underlying needle this is trying to thread is teaching kids to know their audience and adjust their register for it (which is a much broader skill than just whether or not to curse), but I agree that the fucking president ;) doing it gives kids ammo to argue against the rule. Idk if that's a good or a bad thing, maybe just neutral.

It's ridiculous now. It might have not been when we were kids, just that our parents and grandparents weren't able to make the lesson stick.

What is ridiculous is how funny it is when your three year old stubs his toe on the coffee table and yells "oh for fucks sake!", but you have to hide all that amusement.

Good job expressing yourself, little man. It was accurate and concise, but we're going to try not to say that.

>his mom and I do. And all of our friends. And coworkers. And my boss. And his boss. And our CEO. And the fucking president.

>I'm expected

So, who's doing the expecting?

Only half joking: do him a favor and teach him to avoid the passive voice like that.
