A while back when I set up my Google Assistant routines in the bedroom, I set one up for going to sleep. I told it what to do and I told it what to say. When I say "OK Google, good night." The lights go off, the fan comes on and the guy in little box says "Good night Biggie, Good night Smalls, Good night Susan. Sleep Tight."
And, even though, I programmed it that way, it still... every single time, makes me smile.
