LOL!  Love you for saying what pretty much went through my head every day as a teacher back in the day!  Man so many kids were amped 24/7 on all the sugar they ate, the Captain Crunch reference is so apropos,especially in the morning bouncing off the walls or sluggish from binge-watching TV all night or on their phones (yes, phones by first grade, sometimes kindergarten).  ETA:  I'm not against phones for kids since they're great ways to keep in touch/safety for parents who are often at work; I'm talking about the so-called parents who use them as baby-sitting devices and don't take them away from their kids so they can get enough study, play and sleep time.
