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.
