At fifty, a man should be too old to go around flying off the handle, or wandering around on the ceiling. But what could a man do when he had a son who insisted on being a genius?
For a man my age, the middle 50's, life has a number of compensations. There're children—we have two; there's a good wife, and I'm certainly blessed in that respect with Mary; and there's the joy of coming home, slipping on my slippers, having a good dinner, then relaxing with coffee and a pipe. There's no compensation for being plastered to the ceiling. But, more of that later.
The after dinner coffee with a dash of rum in it, tasted very good, and so did the pipe. The meal was satisfying too. Thank goodness for that meal, because it was the last decent one I've had for quite some time. Oh, I've eaten all right, but you'd have to stretch your imagination to call any of it a meal. Can you picture eating food that keeps trying to move away from your face? That is, if you can keep the plate from moving away too?
As I say, Mary and I had just finished dinner, when Jim, our 22-year-old gangly son, who's home on summer vacation from MIT, called me.
Can you come here a minute, Dad?
Sure, I said, heading down the hall to his combination laboratory, dark room, aviary, and just plain bedroom. Fortunately it was a big room so there was space for a bed in addition to all the stuff a boy can collect who becomes enamored of science while in High School, and who consummates the wedding with studying electronics in college.
I pushed his door open a little wider and looked in before entering; a trick the family had acquired when Jim was in the Zoological-Biological, or frog-collecting age. What do you want, son?
Just want to show you something, he said, pointing to the floor. He was bent over looking intently at what seemed to be a sheet of that fluorescent plastic that's used for signs. It was lying on the floor, was about two feet square, and was glowing a dim pink. Whether from light within itself, or from the desk lamp, I couldn't tell.
