Reading Cues

What is the deal with my children's complete inability to read the escalation of their parents' emotional cues? It's bedtime. The kids decide for the hundredth consecutive night that 7:25 p.m. is the perfect time for an "impromptu" dance party. Damn those built-in stereo speakers. We let it go, willing to wash a few more dishes while they exorcise their pre-sleep wiggles. Over the course of approximately sixty seconds, a fever-pitch is reached, break-dancing and full-on floor spins end with head-butts into furniture legs. Suddenly, the volume is too much to take. My husband interrupts for the second time, "Guys, time for bed." As the frenzy unleashes some of the most innovative dance moves of the night, it becomes clear that the kids didn't hear their father. He interrupts again, "Guys, that's it, upstairs now". Oh my God, they still don't hear him. He's abruptly loud and angry-sounding, but their faces glow with bliss and ignorance. When will my kids learn to read?
