The Boy, like his progeny Mason, hated naps and would often fight sleep tooth and nail. But I had a secret weapon:
I had an Amiga 500 back then, and “demo” writers would compete to create the most mind-blowing graphics and sound effects that would run. You might not think it much, but remember this was running on 23-year old hardware. Amigas had special graphics and sound hardware built-in, taking the load off the CPU — the name “Wild Copper” came from the nickname of the graphics co-processor. Modern CPUs are hundreds of times more powerful these days, and don't need all the help.
Back to The Boy. At Mason’s current age, he was fascinated with “Copper,” with its spinning wireframes and scrolling text. When he needed a nap, I’d ask him “Do you want to see Copper?” and he’d sit still to watch it, sometimes bouncing to the music, until he slowly leaned back against me then turned around to fall asleep on my shoulder.
