@tero "You know..."

But if the interlocutor already knows, why would we say anything at all?

(I jest; I say this all the time because it's common where I grew up. It does amuse me, though! I imagine most Finns might think it's a waste of words.)

@jik I didn't know that, and tbh, the fact that my first reaction was "that is so wild!" is probably indicative of why this lack is such problem now. Goodness.
