There’s an old saying where I’m from: you don’t really understand a trade, a problem, or a situation until you’ve personally run into it. I’m not sure I can define it perfectly, but a couple of small everyday examples explain it better than any formal wording.
I later found a more precise explanation: it means that if you haven’t gone through something yourself, you won’t know what makes it work, or where the hidden trick is. In other words, from the outside it looks mysterious; once someone familiar with it takes a look, the answer turns out to be obvious.
That happens all the time with computers. A coworker once asked me to fix his machine because it suddenly couldn’t get online. I checked it and found that the network card had simply been disabled by accident. Two or three clicks with the mouse, problem solved. He sighed and said that this really was one of those cases—you’d never know unless you knew.
I had the same feeling again today.
This morning four of us drove to the county town to take care of some business. On the way there, the car started making a sharp rattling, a kind of clacking noise that seemed to come from underneath, somewhere around the chassis. It wasn’t constant; it came and went. The dashboard showed no warning lights at all. We got out, crouched down, and looked under the car, but none of us could make sense of it. Since the errand was urgent, we had no choice but to keep driving, nervously, half expecting something worse to happen at any moment.
Once we were done, we headed straight to a repair shop. We explained the symptoms to the mechanic and asked him to get in and listen. He laughed and said it was nothing serious.
The problem was right there in the red box: the rubber hanger that holds the exhaust pipe in place had come loose. That let the pipe wobble, and while the car was moving it rubbed against the underside of the vehicle, making the noise we’d been hearing. It turned out to be a very simple fix. And once again, I could only think: if you haven’t dealt with it before, you really are in the dark.
Something similar happened with a bottle of ink that arrived today as a replacement from the Parker flagship store. This one was clearly different from the first one they had sent. The QR code used four colors, while the earlier one had only two. Looking at them closely in hand, even the print quality seemed different. Really infuriating. If I hadn’t gone and scanned that QR code in the first place, I probably would have been fooled and let it pass.
