Black mirror or not, I like this, and can see the enjoyment in this too :D
When I was a kid, when I didn't show up within 5 minutes of being called for dinner, I wasn't allowed to sit down at the table anymore. I then had to wait until everybody else was done, and enjoy a usually cold meal afterwards, and any dessert was usually gone by that time too. And I had to do the cleanup. Suffice it to say, we kids weren't late a lot of times.
And if you wanted to make the ceiling light flash, you had to manually and laboriously flick the switch until a parent yelled at you that it was bad for light bulbs.
yeah. When it was summer and I was like 6 or 7, my parents bought me a cheap digital wrist watch with alarm function, otherwise I would have never made it back to dinner in time when I was outside on the playground, biking around with buddies or playing football (soccer). That was the most "tech" parenting I ever experienced while subject to said parenting :P
I later learned from mom that other parents too kinda relied on that thing going off, so their own kids would go home too when they heard my alarm.
