I once knew a high school teacher who made, in my mind, a curious comment. Referring to a naughty student, he remarked, with a tone of gloomy resignation, “People don’t change.” I knew the kid well. He was what one would call a “juvenile delinquent(不良少年)”. But if schooling held no promise of making positive changes in kids, what was the point teaching?

My own son, Alyosha, growing up, was athletic, energetic, and occasionally hard to handle. But he never showed the least interest in tools, or working with his hands in any way. The result was that he couldn’t tell a screwdriver from a paintbrush. I recall one day, as I fussed under the car, calling out to him to bring me an adjustable wrench(知动扳手). He fetched a pair of pliers(钳子). “No,” I pleaded while trying to hold an oily car part in place. “Pliers.” He went back into the garage and returned with a bar. “No, no,” I corrected him. “The adjustable wrench! For loosening a nut.” To which, in his own defennce, he exclaimed, “Well, I don’t know!”

Years passed. And then, one day, well into his 20s, he told me he had decided on a technical school: machinery technology. I nodded approvingly, but already knew that it was a challenging field, full of moving parts, tools, and dreaded math.

During his period in Coast Guard technical school I thought about him daily, wondering what the outcome would be. I had prepared myself for the phone call telling me that it was just too much and he was being sent to sea as a deckhand.

It didn’t happen. The phone did ring, but it was Alyosha asking me to fly to Virginia to attend his graduation and pin his new rank on his collar. Prouder I couldn’t have been.

As I stood before my son, Alyosha, standing at attention and staring dead ahead, glanced at me. “You want me to help you, Dad?” he said. “Always,” I answered, “but not this time.”

Yeah, people do chance. And, in my experience, it’s usually something to see.
