I think the first time my son said the 'f' word, he got the tone and the body language exactly right for the context in which he used it (a frustrated/resigned "fuck's sake", with roll-eyes and throw-head-back, look up to the sky). He might have been five years old at the time. And back then, I really didn't say it around them very much (out of an attempt to be somewhat responsible).

They're absorbing everything. They're scraping the entirety of your personality to build their own.

Tiny language models.
